Thank you for asking this. It was presented matter of fact and I would not have appreciated that it was something less than settled. The best I can find from googling was rumors and speculation (insert comment in reply with more rumors and speculation). I also don't necessarily think it means someone is a Bad Guy if true. I want people to be able to have anonymous alter egos online if that's what they want and they're not doing any harm.
Isn't Asahi Lina Married to some other japanese Vtubber now? I mean maybe you'd fake all that but I doubt it. Both are more likely real people who are different. The people have totally different eccentricties its really hard to fake that type difference for a long time.
There is. You can easily find by googling "hector martin" "asahi lina" and you will soon find a pile of obsessively archived evidence.
My view, now that Hector has resigned from the LKML both as himself and as Lina, is there is no problem any more. If Hector wants to project a persona, or decide his identity is the persona, or maybe multiple personas, that is fine on social media. People do that. So long as he's not sockpuppeting Linux kernel maintenance, it's fine.
Instead of prompting me to "do my own research" (spoiler: The 'evidence' is lacking and is mostly tedious speculation) you could provide something more compelling
Hector does active work to try and prevent being associated to his Lina persona, mainly by continuing his vendetta against former associate and co-creator of the Lina character, Luna the Foxgirl.
It all depends on the value each and every person brings. Otherwise, I'd rather chose to work with a normal colleague rather than with someone who can't keep his obsessive schizophrenia out of work process. I guess this should be the baseline.
You're right: I didn't answer the question, because I suspect it was asked in bad faith to begin with, given that a simple online search would yield ample evidence. Much of which has already been discussed here on HN.
Given that you've dismissed said evidence provided in other comments as not compelling and/or you attacked the source without addressing the evidence, I think my concern was well placed.
