alt Hacker News> the fact that they additionally ruin respective business models of open source
The what now? Open source doesn't have a business model, it's all about the licensing.
FOSS is about making code available to others, for any purpose, and that still works the same as 20 years ago when I got started. Some seem to wake up to what "for any purpose" actually mean, but for many of us that's quite the point, that we don't make choices for others.
If something is not technically illegal that does not mean it cannot be bad.
Like I said, there is a part that should be illegal, and then part where that's used to additionally harm one of the ways that OSS can be sustainable. The second part on its own is not illegal but adds to damages and is perfectly okay to condemn.
Open source software can have business models, it's one of the ways it can be sustainable. It can work like, for example, the code is made available (for any purpose) and the core maintainer company provides services, like with Nginx (BSD). Or there is an open-source software, and companies create paid products and services on top while respecting the terms of that software and contributing back, like with Linux (GPL) and SUSE/Red Hat.
