I think you're right to be suspicious of everything right now. This article at least frames most of this as speculation. The groyper stuff seems a bit harder to dismiss, since the FBI decided to release evidence that really makes that case, despite them trying to frame it as "antifa."

I'm not super familiar with Vaush or his content so I don't want to immediately assume correctness but in a recent of his on the topic he stated that there is another Tyler Robinson that lived nearby the one in question who was responsible for that donation.
