With most things, the truth lies somewhere in the middle here. I feel like Doug fought the good fight with the More Rake is Better crusade. But this subsequent trolling really is nothing more than shock value and hollow entertainment. But since Doug is done with poker in general, he can do little jabs like this with really no repercussions from anyone in the industry. Will he cross a line that Daniel pursues him legally? Remains to be seen, but I give Doug more credit to do something like that.
As for Daniel, I think a parallel (not completely identical mind you) can be drawn between him and Joe Exotic of Tiger King infamy. They both started out as small time in their respective fields, but as their fame and success rose, they needed more and more money to keep up their appearances and lifestyles. People will always try to shoehorn their way into that lifestyle for their own betterment, regardless of the circumstances. Now will Daniel send a hitman to off Doug? With how topsy-turvy 2020 has been, nothing is off the table.
Should Doug leave Daniel alone not having any skin in the game anymore? Maybe, but free speech is there for you to use. Is Daniel a genial person when meeting fans but also two-faced because of his corporate masters keeping his wallet fat (both Stars and GGPoker) and he really has no other way to go through life if he wants to keep all he has? Certainly.
