OK I'm going to swim against the tide here a bit, sorry.

The google guy is an asshole, but I do think it's important to acknowledge that game developers do have rights over their games and what happens to them, including public display

Right now the balance of power in the industry is such that streamers don't really have to think about it, but I do think it's important to maintain that idea as more than just a theoretical thing

Should it be used to extract rent from small streamers via either the gameplay or music? Not IMO. But, for instance, if the US Army wants to stream a game of mine, I'd like to be able to have a say in that.

If you're a jerk who picks small indie games up to make fun of them, I want to be able to say "don't do that". If you refuse to stream with women, or whatever (publishers don't read this)

Hell, even for other reasons. If someone was just like "I feel that it ruins my creation to have it performed publicly" I would support that. Streamers are called "content creators" but a more accurate term might be "content curators" - it's a symbiotic relationship

And right now the balance is such that if you want to sell a commercial game you need to let streamers have their way, even the Ninjas and Dr Disrespects of the world. Maybe that will be case forever, but I want to hold on to the idea that you do have the right to control that

Streamers have a lot of practiced talent and add value to a "performance" or whatever we want to call it of your work - they have skills I do not have and do not want to develop. But they also need your work, too

When WTWTLW was released, the first thing we patched in was audio controls so that streamers could mute the music and voice in the game separately. Because some streamers like to read text to their audience. We did it, of course, but it broke my heart a little.

I worked with voice actors who are incredibly good at what they do, some of the top names in the business, and they delivered amazing performances. And the idea that that might be replaced with someone doing goofy voices or whatever... it was a little rough

I'm not a big fan of copyright at all and I wish there were a different system, but that's what there is right now. I hope that maybe an alternative system could be developed where creators could assert rights in a less-aggressive manner

If you're a developer, you DO have the right to control how people display and perform your work for the public. Depending on your aims it's maybe not a good idea to exercise that, but you do have it.
