I used to watch The Wan Show which I guess is more of an unfiltered look than the edited videos. But yeah, kinda.
There were numerous times when he'd openly criticise a colleague, or just like... undermine them? And then realise he was looking like an asshole and awkwardly laugh to try to pass it off as a joke.
Yeah, but from those videos it's unclear whether that's an act or real. Iirc there have been Reddit AMAs about 'what it's like to work for LTT' and the tone there was always 'It's intense' and 'His YouTube persona is not an act' but never anything really damning. The ex-employees there seemed to respect him, but did see it as a place with a harsh work culture and little space for a personal/family life.
I think the fast growth accelerated some bad tendencies in the culture, and now it's all a complete mess that got away from them. The CEO change in hindsight seems quite ominous, now.
