I have pixeldroid, Tusky, and TubeLab installed but I rarely use them compared to Lemmy. It’s not that I use the proprietary alternatives, I just don’t feel the need to use a messaging app that you have to include images with, or limits the amount of characters in your message.

I sometimes use NewPipe or Odysee because Peertube doesn’t have the content I want, but also not very often.
