Linus wasn’t accused of sexually harassing anyone. His company was accused of being a hostile work environment with sexual harassment by a former worker, but the accusations weren’t against Linus himself. LTT hired a 3rd party law firm to investigate - LTT said the law firm basically said there wasn’t legal liability based on the documentation they could find and LTT used that to absolve themselves and threaten to sue the accuser if she said anything else.
But this was an LTT hired lawfirm and LTT themselves reporting on what the report said - and since it’s confidential you kind of just have to take their word that they’re accurately reporting the findings. Further there were initially some corroborators of Madison’s story who retracted and apologized quickly (assumingly after being threatened with legal action - Aprime is the example). Besides that a lot of the accusations were things that happened in person that wouldn’t necessarily leave a digital trail so it’s possible even if the 3rd party investigation was completely unbiased that everything Madison said was still true.
In the end believe what you want but it seems slimy enough that I stopped watching.
