I left for the same reason. I browse on mobile and I genuinely tried for years to find in the official app where to just type in a subreddit. Like if I just heard about and wanted to go to r/whatever, there was no field to type in ‘whatever’. You could search, there was a dropdown of pre approved subs, or subs that passed a subscriber count, very rarely did it include what I was looking for. On Apollo it would take you to the sub you typed in. If advertisers or shareholders demand an unusable website then great I won’t use it.
