What's this about?
LWN covers a continuing AGPL licence violation in a popular 3D printer's software stack, and the thread turns into a debate about whether the licence is enforceable at all.
What exactly is the AGPL?
A licence saying that if you use the code, you must publish your modifications — and unusually, that this applies even if you only expose it as a network service rather than shipping software. It closes the loophole where companies build on copyleft code and avoid sharing by never distributing a binary. As several commenters note, it has never been tested in court, so its strength is partly assumed.

- Practical mitigation gets top billing: run the printer in LAN mode with OrcaSlicer and an open reverse-engineered networking plugin, with one commenter confirming zero external connections.
- The jurisdictional problem — whether a China-based company can be sued at all, and whether import bans are the only real remedy.
- A specific legal strategy: litigate in the Court of International Trade, which can block imports via a temporary restraining order.
- A sharp dissent calling the AGPL a non-free licence masquerading as a copyright licence, whose logic has never been adjudicated.
- Frustration at explaining licensing to a maker community that largely does not care.
