I use uBlock Origin and its :style() feature to remove and modify parts of websites that I don't like.
I don't block user comments on PHP doc pages out of spite, I do it because they are very long, making it harder to scroll vertically on the actual documentation.
You need a thick skin to maintain free software, and that's not something that you can grow... either you have it or not. It's not for everybody.
The biggest mistake some software maintainers make is showing empathy for abusive and unreasonable users. Most of them simply deserve to have the door slammed in their faces. If you can't do that, then you'll lose your time and stress yourself.
