To be fair, their twitter account got suspended, I know stacks of random people who've had their accounts temporarily suspended for one reason or another, twitter is a bit mental when it comes to account suspensions tbh. FYI for what it's worth Alex Jone's twitter account is up and running right now.

If Facebook and Youtube want to make a platform where people don't have to put up with things like Alex Jones, then they're well within their rights to do that - but I think it's a mistake and I think they've embarked upon a difficult road. The amount of decisions they're going to need to make are infinite - essentially, it won't ever be fair - (as evidenced with groups such as Antifa and other dodgy groups where we both agree - the policy isn't working, or being applied fairly)
I think as far as advertising goes, - yes I understand that Youtube/Facebook/Etc have to make money, however we could get to a stage where the only content that's allowed on the platform is there to appease advertising companies, in the sense that anything that's controversial or naughty gets denoted or removed because nobody wants to have their advertisements associated with it (regardless of the amount of clicks)
We could end up with a situation where people start to lose trust in Social Media because the platforms are there for the advertisers, not for the consumers or content producers, trying to perform censorship like this - in a world where the definition of something offensive, changes every other day, might drive people away from the platforms - or cause different platforms to be created that become safe-havens for maniacs.
Interesting argument on Bill Maher;
