If I wanted to go rogue and insert a backdoor in a project of mine, I'd probably create a new sockpuppet account and hand over management of the project to them. The above is worringly compatible with this hypothesis.
OTOH, JiaT75 did not reuse the existing hosting provider, but rather switched the site to github.io and uploaded there old tarballs:
If JiaT75 is an old-timer in the project, wouldn't they have kept using the same hosting infra?
There are also some other grim possibilities: someone forced Lasse to hand over the project (violence or blackmailing? as farfetched as that sounds)... or maybe stole Lasse devices (and identity?) and now Lasse is incapacitated?
Or maybe it's just some other fellow scandinavian who pretended to be chinese and got Lasse's trust. In which case I wish Lasse all the best, and hope they'll be able to clear their name.
Is the same person sockpuppeting Hans Jansen? It's amusing (but unsurprising) that they are using both german-sounding and chinese-sounding identities.
That said, I don't think it's unreasonable to think that Lasse genuinely trusted JiaT75, genuinely believed that the ifunc stuff was reasonable (it probably isn't: https://news.ycombinator.com/item?id=39869538 ) and handed over the project to them.
And at the end of the day, the only thing linking JiaT75 to a nordic identity is a nordic racist joke which could well be a typo. People already checked the timezone of the commits, but I wonder if anyone has already checked the time-of-day of those commits... does it actually match the working hours that a person genuinely living (and sleeping) in China would follow? (of course, that's also easy to manipulate, but maybe they could've slip up)
Anyhow, I guess that security folks at Microsoft and Google (because of JiaT75 email account) are probably going to cooperate with authorities on trying to pin down the identity of JiaT75 (which might not be very useful, depending on where they live).
(I still think it's like... 60% a typo? don't know)
Anyhow, other people called the CCing of JiaT75 by Lasse suspicious:

Lasse is of course a Nordic name, and the whole project has a finnish name and hosting
