You don't know this, but this Greekgod guy in particular was known to harass and troll Antoniades' twitter constantly. He uses the same name for YT and other blogs, and he's constantly bad mouthing them. So I don't quite agree with you saying that it was in poor form of him to respond this way, especially when this guy in particular harasses him constantly.
It just sounds like you're trying to make this into some sort of anti-consumer action. When it clearly isn't.
Anyway, I'm curious if you think Hideki Kamiya's twitter responses fall under poor pr. Cause he goes as far as insulting people for asking him simple or poorly thought out questions.
And also - Tameem's response wasn't even to that comment posted to go with it. Tameem was responding to a video of Dante just spamming Angel Lift between enemies to stay airborne, and saying that the game needed to be fixed because you shouldn't be able to stay in the air that long. The "don't have a fix for face-palming until you bleed" response was because of the absurdity of complaining about a mechanic in game that was working just as it was supposed to.
