Reddit has been trying hard for years to move beyond being a discussion forum to another mindless scroling app.
The reason is because in the time people read one discussion thread they only see one ad, but scrolling memes, etc they will see many more. It makes the ads much more valuable.
(Copied from the thread on /c/Quark's)
I quit as the top mod of /r/StarTrek in 2021 in protest against Reddit's platforming of vaccine disinformation subreddits. Then in 2023 during the API protest, myself and several of the remaining mods (including mods from /r/Risa and /r/DaystromInstitute) started StarTrek.website.
The consensus I've seen on Lemmy has been largely "we don't need to spread the word about our open platforms because Reddit will do something stupid again and there will be another protest and Lemmy will be promoted there". So I hope we can take this as a lesson that we can't rely on platforms being shitty in order to switch society over to open standards. We need to do our best to make Lemmy/Mbin/Piefed good as well as known.
