After watching the videos, and the analysis from Legal Eagle, I find the criticism a little dubious.
"Rigged challenges" is how he introduces surprise things mid-video, like "I'll give you $10,000 if you quit now, but your team loses a team member!" It's obviously part of the show and participants agree to it happening before hand.
"Knowingly hired a sex offender". Well? Should everyone on the sex offender registry be jobless forever, or what is the point? The person in question was convicted when he was 16, and was hired 7 years later with nothing indicating he would reoffend. Don't we have courts for justice? Instead they should never be hired as punishment? To me it sounds commendable he's not prejudiced against people's past.
"Attempted to silence anyone" Did he? There is tons of people criticizing him and I only heard about one cease and desist. Do we know that C&D was baseless?
That DogPack guy seems to have created his YouTube channel solely to attack MrBeast, do we have anyone more trusted?
Like many, I find the MrBeast videos a cancer of YouTube, which makes hearing any critique of him convenient. But I don't like assuming, and I have a feeling the DogPack guy has an agenda and isn't offering an objective view.
