Well... being the little pathetic sarcastic corporation hating person that I am, I would gess they paid him to praise how well they ported the 5e system into the digital realm since they hope it gives them the public relations to continue their narcist abhorrent corruption of it.
Sometimes I hate being right.
And I must admit I was deviously satisfied when they lost after a long boring combat.
Honestly.... yeah. I wasn't at all pleased with Jeremy Crawford going all "lol do whatever, it's a different platform". I would so much prefer them to actually try and get the PHB rules right first and foremost.
