I have sent countless small bug fixes even before, to tools that I use that I could dig into when something was off... No big heavy lifting, but plenty of "tinker on your tools" stuff. And I don't think what I did was that special, so maybe the experiences are different?
The current LLM-driven stuff seems to break down the expectations, and now there are a lot of places which just ignore anything I send in (the same tinkers as before), generally, for a while. Though there are some tools that picked up the pace and actually react faster (so YMMV here too).
But there are few things more frustrating as being half-way. Case to point is LM Studio. It's closed source, has bugs (duh!), and there's at least a GitHub issue tracker to report the bugs -- but then by and large nothing happens to those reported things. It's almost worse than not having an issue tracker (then I could justify never to really touch LM Studio again, this way I keep hoping against hope that reports will turn into fixes and thus I keep using and keep reporting...)
That's my biggest gripe with open source software. It's not really the open source part that's bad, but when projects turn into major projects with a substantial user base, I think the owners have an obligation not to delude their users into thinking they have more say than they actually do. Plenty of big projects leave their issue trackers public and have docs that encourage community contribution, yet effectively ignore user submissions unless perhaps someone with a name raises an issue. I completely agree that allowing users to waste their time believing their issue or pull request can make a difference is actually worse than not allowing public submissions in the first place.
I'm not sure why I seem to be in the minority on this. Maybe I've just had bad luck in that most of the issues and PRs I've submitted to open source have been ignored. Hell, I'd prefer a "thanks but no thanks" or even "fuck you" over radio silence. The typical response to this frustration of mine is "just fork the code, bro", which is absurd because forking should be a last resort for software that thrives from having a community.
The solution for this is to pay open source maintainers for their attention. If I want them to review and merge my bugfix I should attach $1000 to the PR.
