But basically it started when Gamers Nexus called out some issues LTT had with testing methodology and also an incident where LTT accidentally auctioned off another companies products that they had reviewed poorly.
Then Linus responded pretty poorly (and ended up stepping down as CEO and is now a chief creative something or other iirc)
Then a former employee tweeted about why she left LTT and accused LTT of having a toxic workplace environment. And specifically said she had been sexually harassed by a coworker but not taken seriously.
There's no court case, LTT just did this to clear their name basically.
