I'll start out by saying I don't personally believe he himself took the game down.
But this community's biggest problem is hating dsp so much that you'd lose any feeling of fairness whenever he's right on an issue.
Phil is right to DMCA takedown blatant raw restreams or uploads of his streams. No matter the mental gymnastics or analogies you want to resort to, they are not fair use and he's 100% allowed to take them down.
This guy made an asset flip of a game, put his face on it and is selling it at $5.00. It is objectively using his likeness, it is objectively without permission, and it is not in fair use.
Phil is, and will always be a fucked bitch and a salty subhuman scum fuck, and I will always find enjoyment in his misery, but he is LEGALLY in the right to take shit like this down. It's just a really bad look for him (or his "team", and it makes him look even more like a bitch.
