You are seriously trying to claim using a program to LEGALLY make another program is even comparable to someone willfully violating copyright laws and making money from it? That is just beyond laughable.
Maybe I should have worded it differently, though profit doesn't change legality.
You are not allowed to profit from someone else's work, plain and simple. Playing a game is not work, recording it is not work. Doing commentary? That itself is not illegal, but including video of it IS. If they want to upload just the audio, that is fine.
Ugh, read my comments again. It depends on how much you use. A few pictures is fair use, hundreds is not. Using like 2 minutes of video could be considered fair use, 2 hours would not be. You bring up the creator, and the creator has made it clear how they feel.
