Our Freedom of Speech

Why is our freedom of speech being taken away during the chats on Twitch.tv's MASL_soccer? The last Strykers game was emote only and then the chat was limited to followers who'd been there for more than 3 months and that's how the Milwaukee Wave vs. Monterey game is right now. 

We can't mute people in the actual crowd at games, so what is a better way to address the issue?
