I suffered from this a few months ago as well. The space and bandwidth flatpak was taking for about 2 small cli applications was obscene. Like 30gb all because it had accumulated about 10 nvidia drivers. I found the issue on github and it was closed as intended behavior. I install alot of rust apps from source and updating them from source was faster and easier than updating flatpak just due to the overhead of maintain those drivers.
That and the fact that every app has to be run through an alias or a. overly verbose command made me discount flatpak as a serious project. You can’t ignore UX to that extent and just rely on technical merits.
He was supposed to have made his money before FTX by doing crypto currency arbitrage, but people have gone back and done the maths and his supposed profits were mathematically impossible (or just exceedingly improbable). The fact that his crime here was investors money went straight into a slush fund for his and his friends personal use suggested he didn’t make that much money first either.
