This isn’t really accurate. Mbin does what Lemmy and Piefed do (Reddit replacement) plus what Mastodon does (twitter replacement). They’re just in different tabs of the interface. You have the option of microblogging if you want, but threads are still pretty much exactly the same compared to Lemmy or Piefed.
Basic scrolling feels so much better. And I don’t think it really makes a huge difference for battery life, so I always leave if at 120.
