I think it’s a huge battery drain compared to all the alternatives, liftoff for example with Lemmy despite using it just as much as I did the official app in testing consumed less than half the battery life. Apollo also consumed about half of the official Reddit app while using Reddit so I dunno.
Also the constant promoted posts are just horrible to deal with.
It was the case prior to 2015 or so before the amd open source drivers actually became good.
They didn’t exist prior to 2014. Amd also required proprietary drivers and were a significantly worse experience than Nvidia back then.
