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.
