I say thanks to open source maintainers all the time! 😄
Anyway, while a wall of profanity and fuck you is clearly not ok, I do disagree with this:
The maintainers ship this for free. People run production businesses on top of it, for free.
Just because you offer something for free doesn't absolve you of all moral responsibility. I'm not saying you have a lot of responsibility, but "it's free so you can't complain!" is pure nonsense.
Go and give some kids free poisoned sweets and see how far that gets you.
