I think you are making a big mistake if you think that Bitcointalk users opinion doesn't matter. Unlike other platforms, there is almost no censorship here, what it is written stays for long and is easily retrieved by Google, moreover the biggest people of the crypto industry have an account here.
Twitch seems to have been a powerful tool for promoting casinos but now it has ended and casinos need to find other ways to attract new customers. I don't know precisely what is the average loyalty lifetime of a customer at an online casino, but I guess it's very short, hardly more than a whole year on average IMO.
According to this article, only 20% of customers make more than 5 deposits, and only 50% make a second deposit. So it would be a big mistake in the long run for a crypto casino to disregard the central place of the crypto universe IMO.
It is obvious that bitcointalk matters which is why they are caring, I am only saying that if they didn't care at all, they are so huge right now that it wouldn't really cause any harm to them at all. But that is not important right now and you are right, thats not the path they are taking anyhow.
However, Stunna came in here, explained the whole situation, it was only raw data, and even though thats bad too, it wasnt any money at all and people claiming things like "10 million was stolen!!!" without any proof are the type of reason why people may end up stop caring about bitcointalk and the "freedom of speech" here, because many mistake freedom of speech with freedom to lie freely, and thats not what it means.
