A 3D printing company weaponizes legal threats against an open-source developer, a PlayStation emulator draws a line against AI slop, and one of the most-watched terminal apps finally opens its code. Here’s what matters today.
Bambu Lab legal threats shut down OrcaSlicer fork — developer pivots to fully open-source printers
Independent developer Pawel Jarczak shuttered the OrcaSlicer-BambuLab project after receiving a cease-and-desist from Bambu Lab, the 3D printer manufacturer. Jarczak’s fork restored direct cloud printing features that Bambu Lab had removed in January 2025 to force users through its proprietary Bambu Connect middleware. Bambu Lab accused him of reverse engineering its software and violating its Terms of Use — despite the project building on AGPL-licensed code. Right-to-repair advocate Louis Rossmann offered $10,000 toward legal fees if Jarczak would put the code back online, but the developer has instead announced a pivot toward supporting Klipper-based open-source printers. This is a textbook example of the tension between open-source slicer software and vendor-controlled hardware ecosystems: Bambu Lab sells printers that benefit enormously from community-developed software, then uses legal threats when that community exercises the freedoms the license was designed to protect.
RPCS3 bans undisclosed AI-generated code submissions — “learn how to code”
The team behind RPCS3, the open-source PlayStation 3 emulator that has made 70% of the PS3 library fully playable, announced a new policy banning autonomous AI agents from submitting pull requests without disclosure. The problem: a rising tide of untested, unverified AI-generated code submissions that waste maintainer time reviewing garbage and, in worse cases, get merged and break functionality for real users. The new rules require contributors to fully own and understand all code they submit, disclose the scope of any AI involvement in PR descriptions, and accept that repeated violations mean a repository ban. The team was characteristically direct: “learn how to debug, code, and leave behind something useful to humanity when you’re gone, instead of peddling slop.” RPCS3 is far from the first project to grapple with this — but as AI coding agents become more autonomous, expect more maintainers to draw similar lines. The fundamental issue isn’t AI-assisted coding; it’s people submitting code they don’t understand to projects they don’t contribute to, treating open-source maintainers as free QA for their AI’s output.
Warp terminal open-sources its Rust client under AGPL — with OpenAI as founding sponsor
Warp, the AI-first terminal that has positioned itself as an “agentic development environment,” released its client codebase on GitHub under AGPLv3 (with the UI framework under MIT). The repository hit 56,000 stars within a week. Built in Rust and running on Linux, Windows, and macOS, Warp differentiates itself with a block-based command interface and built-in support for AI coding agents including Claude Code, Codex, and Gemini CLI. The interesting wrinkle is the contribution model: Warp is leaning into what it calls “agent-first workflows” where contributions are managed through Oz, its cloud agent orchestration platform, powered by OpenAI’s GPT models. OpenAI is also the founding sponsor of the repository. The open-source purist community has mixed feelings — the client is open, but the AI orchestration layer remains firmly proprietary. An independent fork called OpenWarp already exists, letting developers plug in any AI provider with keys staying local.
Dell and Lenovo become premier sponsors of the Linux Vendor Firmware Service
Two of the world’s largest PC manufacturers stepped up to become premier sponsors of LVFS, the service that delivers firmware updates to millions of Linux devices via fwupd. A premier sponsorship means $100,000 in annual dues — real money for a project that has shipped over 145 million firmware updates and quietly solved one of Linux’s longest-running pain points. Dell and Lenovo join existing sponsors Framework Computer and the Open Source Firmware Foundation, with the Linux Foundation and Red Hat providing engineering support. If you’ve ever had a Linux laptop just silently update its firmware through GNOME Software without you having to hunt for a Windows-only update tool, LVFS is why. This sponsorship is a signal that major OEMs now consider Linux firmware support a first-class engineering concern, not a nice-to-have afterthought.
Ubuntu’s X account hijacked for crypto scam amid ongoing DDoS attack on Canonical
On May 7, attackers compromised Ubuntu’s official @ubuntu X account and used it to promote a fraudulent “Numbat” AI agent supposedly built on Solana, directing followers to a phishing domain (ai-ubuntu.com) registered just one day earlier. The site lifted real Ubuntu AI documentation and wrapped it around a fake “$UM token” airdrop with manufactured urgency via a countdown timer. The attack arrived while Canonical was still recovering from a sustained five-day DDoS attack that began May 1 and disrupted over a dozen services. The combination — sustained DDoS to exhaust the ops team, then social engineering during the chaos — suggests a coordinated campaign rather than an opportunistic hack. For any open-source project with a large social media following, this is a reminder that brand trust is an attack surface.
EU to present Tech Sovereignty Package on May 27 — open-source alternatives gain momentum
The European Commission is expected to unveil its “Tech Sovereignty Package” on May 27, including the Cloud and AI Development Act (CADA) and Chips Act 2.0. The legislation would restrict EU member governments’ use of U.S. cloud providers for processing sensitive data — though the rules would not extend to private-sector companies. European governments have been exploring homegrown and open-source alternatives to U.S. tech platforms since February, and the Commission has already launched a €180 million sovereign cloud tender. For the open-source ecosystem, this is potentially transformative: if EU governments are mandated away from hyperscaler lock-in, the demand for open-source cloud infrastructure, AI deployment platforms, and sovereign alternatives could surge. This connects directly to the vendor lock-in concerns that surged 68% in the 2026 State of Open Source Report — driven largely by European organizations.
