That's the interesting part. Linus wanted to make his yt channel a company. Created LMG with a loan and all. Cool. But that means that now the company, and by extension Linus himself as the owner, is morally responsible for all that happens within their walls. That's also part of the initial ethical failure, I don't mean they cause or are to blame all the time, but they're responsible for dealing with it.

Linus might not have harassed anyone himself personally. But, if one of his employees harassed another of his employees, he is responsible. Worse, if he know and did basically nothing, then LMG neglected to act on its duty of care. Same reason why, when one employee goes in public to diss out and trash talk a competitor, then it's as if it came out of Linus mouth, because it's LMG speaking.

"But I was busy with emails" is not an excuse, or "I didn't know", isn't either. Your company your responsibility.
