There is no bad behaviour. Defending oneself isnt an unreasonable thing to do. GrapheneOS is entirely funded by donations and receives a lot of donations to this day. Them defending themselves is not an existential risk, the attacks against them are.

Why the scare quotes? Being right is the literal opposite of bad behavior.

If you have zero consideration for other people, sure.

"I can't believe you wrote this terrible code. You clearly don’t understand how concurrency works. Do it again."

Technically right, but when you run out of people who actually want to work with you, you'll be writing the code yourself.

What's worse: good work that I get to do myself, or bad work that I'm forced to accept anyway?

Which "bad behavior" are you talking about?
