Ultimately I'm not too worried about this, simply because of how the money flows. Twitch is owned by Amazon. YouTube is owned by Google. If it ever comes down to copyright infringement, Google and Amazon both have billions of dollars to lose by not defending the creator from the lawsuit (they don't want a negative precedent affecting their bottom line). So both of these companies could profitably invest literally billions of dollars defending the creators. Thus, I'm not worried. Not only is fair use a reasonable argument, they can simply make the legal proceeding unprofitable for the game companies. Reputations are at stake as well, which is why you only see tiny companies you've never heard of DMCA-ing streams.

The game companies too have to like videos and streaming. I have only ever played games that I've heard about on YouTube and Twitch. I imagine I'm not the only one.

Disclaimer: I do not work for Google anymore, so this is even more of my own opinion than usual ;)
