I used closed and open source software. It just feels much better if I see a bug, fix it, place a pull request and be done with it, than discuss with some devs in a bug tracker if and when they want to fix a bug I hate.
It's no surprise that most open source software is clunky and hard to use whereas closed products always have that visual polish.
And often big projects have, similar to closed source software, rather ugly workflows where you have to discuss stuff before you're assigned to a bug and then have to send it patches and what not.
A good review process is important or else everything ends in chaos.

A lot of open/free projects are indeed "hobby" projects (and not in a good way) -- but to claim that all of them are bad? Compared to what? The shareware scene from the 90s?
Creating a Pull Request doesn't mean that the developer of the open source project has to accept it verbatim if it doesn't fit with the 'vision.'
[Also, I'm pretty sure that the parent to your post was talking about bugs that probably don't involve visuals.]
