There’s a part 1 to this video that goes into it. Basically:

• videos are faked (reality level TV stuff - making the timers look like they’re still counting down)
• there was a person who was recently on staff who was a sexual deviant named Ava Kris Tyson who also seemed to be obsessed with teenagers and ran a discord server talking about inappropriate stuff (this is worse than my description sounds)
• Beast was on this server for a time but doesn’t seem to have been an active participant
• Illegal lotteries from the Streaming “giveaways”
• claiming his chocolate is “healthy” and encourage kids to eat it to have a chance at randomly winning a prize
• in Aus, having an app for the chocolate that says you win a prize when you pull the slots but you actually don’t win anything (basically getting triple 7s and getting told you win nothing)
• safety issues with the beast games, moving to Canada so no union workers can join, etc.
• this video explains some horrible stuff Mr Beast and team did for a single video

Really the biggest deal I think is the illegal lotteries. Because those are actual criminal acts

Just people finding out that Santa isn't real but in fact a company which uses psychological warfare to sell you something that is bad for you.

A story as old as capitalism.

Since nobody pointed it out yet there's also controversy because his friend was being inappropriate with and allegedly touching kids using the fact that they work with Mr beast. That just came out before all this. And Mr beast fired them, but there's a lot of discord messages that Mr beast was in on as well where some of the inappropriate stuff towards kids was happening as well
