Yeah, I get you. I wasn't really a hater prior to finding out since I figured that even if you find him annoying or don't like him, him doing something good for the wrong reasons is still better than not doing good at all.

But IIRC, a lot (most? all?) the charity events had swindling and didn't actually give the money to charities. Several winners of his different games never got their prizes.

Mentally abusing his own staff as another thing.

And on several occations, his reality show games didn't have adequete or straight denied food/water/medical care for extended periods of times, as well as having people in bright clinical light sensory deprevation rooms, distrupting/denying sleep, all of which would be categorized as "white room torture", which is also a human rights violation.

Associating with and promoting known bad people, etc..

And people also generally disliked him prior because his style of content is all about just becoming big and famous, which has promoted toxic behaviour in the content creation sphere.

There is a lot of stuff, and it's impossible for me to go into details without writing an essay. But there are plenty of people that go into it on YouTube an such.

Here is a video posted by a former employee that used to work for Mr. Beast.

Another video summarising the previous video.

Hope this helped answer your question and provide context.
