For me it's just the … insulting, hostile vibe of most of those LLM-based projects.
A lot of them don't appear to have been developed in good faith to fulfil one of the person's needs or interests, or because they enjoy software development.
Instead it often looks like they were created solely for ulterior motives like grifting money, fame or deceiving others. Often it even seems like the sole intention is actually to upset people on purpose, like "haha, look how mad this makes the anti-AI folks! look how much smarter and greater I am than you!!"
The program itself is then completely meaningless and irrelevant, just a means to an ulterior end.
It all has a similar vibe to those neo-nazi/alt-right "forks" of popular FOSS projects that keep popping up occasionally, like Redot (Godot), PolyMC (MultiMC), XLibre (X11), Sneed-whatever it was (Audacity).
They often don't make any technical progress at all; they just exist specifically to pretend that there is a serious alt-right software project that has some kind of authority, and to thereby upset the 'enemy'. They often go under in just a few months because they end up realising they aren't actually interested in programming, they just wanted to participate in a culture war.
