This is unverified so maybe that should be included here since it's getting upvotes. I'd rather delete it tbh but can't. Or if someone can just flag this post for me, thanks.
(And like, he might simply not have had a YouTube account with his username set--so as to effectively prevent someone from doing this today--as there is no reason to have done so unless you really cared about your username.)
That said, he was apparently a bit of a software developer (with an account on GitHub), so maybe he in fact really did set this all up ahead of time? But the profile pic just seems way too ridiculously on the nose, frankly...
Also, if you are going to do this, would you really not have your YouTube account linked from anywhere?! He has an account on all of Twitter, Facebook, GitHub, and even Linktree, and yet no link to this YouTube account.
Didn't know this (not a YT user as such) but I won't delete the comment for thread history sake.
It does appear it may be bogus.
