Personally, I just don't like the guy and his vibes. But I wouldn't tell random people online to avoid him, he's not that bad.

There was also that self-driving car video which turned out to be really scummy.

He created fake science experiments to sell products and slipped them into normal videos, like the video where he claimed wet wipes are flushable, then created a fake experiment “proving” they were flushable. He’s incredibly untrustworthy and also, not a scientist! He’s an art major or business, can’t remember which.

people are annoyed that he sold to a venture capital business

but then not realizing that so far, their quality improved, while also releasing more videos
