This has to be fake rage bait. No one is THIS entitled.

I've seen a lot of similar things in gaming communities. This is almost certainly genuine entitlement.
I do believe I've seen comments on Arthras' video about people who played with OP as well, and afaik, the pattern matches with what we see here.
All signs point to "he's serious" and I would be more surprised if this was genuinely a bait.
