Quoted from PanzerFreak:

What happened to Cary reminds me of what occurs regularly in video games media. I've been following a video game website / podcast for a decade called Giant Bomb and they don't hold back when it comes to criticism. This approach had led to Giant Bomb not receiving free games (review copies) from some publishers as well as not being invited to some industry related events. Some of these game companies prefer to deal with YouTubers that will not say anything bad about their products. Giant Bomb loses out on the freebies and doesn't care as they have integrity and the respect of a growing audience.
To get around the situation above Giant Bomb just buys their own copy of the game, problem solved and they keep their integrity. That's a bit harder to do with a $6k - $9k pinball machine versus a $60 video game. If Carl buys his own Turtles, or goes to another location / friends house he can stream all he wants. The problem Cary encountered may be with a location that is somehow partnered with Stern or at least getting freebies from them for launch parties.
On a side note the co-founder of Giant Bomb, Jeff Gerstmann, was once fired from GameSpot after working their for 10+ years due to his criticism of a game in a video review where the publisher of the game was providing ad dollars to GameSpot. That caused a huge uproar back then and led to a ton of fans leaving GameSpot and then Jeff eventually forming Giant Bomb.
