In my opinion GitHub is seriously good software, but it is awkward when FOSS software is developed on it instead of on Codeberg, Gitea or another FOSS platform.
Discord is actually a security risk, it walls information off the outside world (compared to a forum or IRC server) and incredibly difficult to find information in even when you're in the server (as opposed to documentation or a forum)
Matrix has 2/3 of these issues, so it being FOSS aside I very much would hate it when development discussion and software documentation is done through Matrix, as well.
JetBrains' AI code suggestions were only trained on code where authors gave explicit permission for it, but that's the only one I know from the top of my head.
Most chat-oriented LLMs (ChatGPT, Claude, Gemini...) were almost certainly trained using corporate piracy.
They're helpful to my deaf ears, even when they're wrong (50% of the words) they do give me a solid idea of what is being said together with what the audio sounds like.
With it, I get almost everything correct. Without it, I understand near to nothing.
This only goes for English spoken by Americans and sometimes London Britons, sadly, nothing else get detected nearly as good enough, so I can't enjoy YouTube in my native language (Dutch), but being able to consume English YouTube already helps a lot!
Doesn't mean it'll be added in an open source application... There has to be a dev/some devs willing to implement that, they can't force volunteers to implement features because of the selling value it'll have.
Sounds about right.
