I agree with all the comments so far but would like to add my own thoughts. Users are not important. Personally I moved to lemmy because the quality of discussion on reddit dropped so much.
This has been my trajectory:
avid reddit user and content creator there (not sure if the right term) 2016 - 2018
lurker from 2018 to 2023
completely dropped reddit and moved to lemmy
My hope is that we can have the same kind of content and discussion in pre 2020 reddit
