The weirdness is much less visible in Primeagen's content nowadays (albeit I've almost completely stopped watching it so maybe it's now getting more overt?), I'm not overly surprised devault has nothing concrete to point at - in fact I wouldn't be surprised if he has scrubbed the more egregious things from his youtube channel.
It's never been big attention-grabbing things but more a certain level of crypto-fashy offhanded remarks and general vibes - been brought up in the weekly snarks a few months back.
The biggest recent criticism I could make is having DHH on fire over an hour with allegedly no pushback on how terrible his "distro" is given how much primagen supposedly prides himself on his technical prowess. Then again, he's not using omarchy himself so what does he care if the rubes in his audience get duped into trashing their machines?
