I agree. Sometimes its easy to forget that these online celebrities are people. Linus is a person, as flawed as any of us. He let his ego get in his own way, and took sharp criticism of his company as personal attacks - which is an obviously easy thing to do. The important thing to look at is whether or not LMG / he learns from this, which I'm sure they will.
The only truly concerning thing to me is the Maddison stuff. That I'm reserving my judgment for. I don't doubt her account of things, but it's simply one side to a story. That she self harmed to get a day off is very worrying, but it's also a massive red flag. That is a pretty extreme escalation. Clearly she wasn't stable, but did LMG cause the instability or just contribute to it? Either wouldn't be ok, but she was a person acting abnormally - and that's a lens that deserves extra consideration.
I don't intend to stop watching LMG for the time being, and I'll withhold my judgment for now.
