Programming

I think it is common knowledge by now that the kernel community is a rather toxic space where abuse and elitism are the norm rather than the exception. If you are unwilling to put up with that, it's probably the wrong community for you to join.

I would absolutely try to sue in this case. My experiences with very experienced specialists is not stellar at all. The amount of gatekeeping and sheer arrogance is frightening. I get it, nobody wants to work on the kernel. It’s an underpaid (presumably) and underappreciated task. I would probably become an asshole as well if I dedicated 90% of my free time to fixing obscure bugs in even more obscure architecture.

Disclaimer: I‘m not a kernel dev and my experience stems from interactions with maybe 100 people of varying stages of proficiency. Sadly, the more proficient, the less friendly they often were.

Edit: the amount of downvotes you get for saying something unpopular without being violent or abusive is showing the lack of guts to discuss something in a civilized manner. Shame on you.
