Nope. Most of the relevant software is OSS made by hobbyists. ComfyUI, llama.cpp, etc. For example, Nvidia is building stuff based on ComfyUI, a GPL-licensed application.
My complaint is about people ignoring the license of open source software made by hobbyists. I disagree with your ignorant "AI fans" generalization.
Companies are more risk-averse, though, and hobbyists on Reddit don't have the money to do anything serious with this software.
