My take:
I understand Wolf's point. The guy is having a hard enough time adjusting to life without his dad and best friend. They are, essentially, a small family. He is the only child. And they had a deep connection. So with Wolf being in the public eye (which was his choice) he's continually hearing all this stuff about his dad and honoring his dad. It has to be tough.
That said - Wolf seems to take things way too personally. That comment about Eddie had nothing to do with Wolf. Eddie just wants to see something appropriate done for EVH. And he's not wrong.
The other side of it is Wolf knows, I am sure, what the hold up is, and he's not going to sit there and throw people under the bus either. Yeah, we all suspect (and we're all probably right) that it's squarely on DLR's shoulders. And if you do a tribute with just Sammy and say Gary Cherone, sure, the vocals will be better, but it wouldn't be quite...right, without Dave.
Bottom line - Wolf needs to stop reacting to this shit. The man is in pain, still, two years on. It took me two years to move forward, in a meaningful way, after losing my mom. It differs for people and it sucks Wolf is struggling. But reacting to random shit on Twitter isn't helping him.
