I just signed up through this lemmy.world thing. Was that wrong? Should I not have done that? This federation thing could be better explained.
Nonetheless, I find Reddit's disrespect for its users to be an ill omen. A 1-month deadline for anything as deeply ingrained as 3rd-party apps sends a clear message that Reddit doesn't want to compromise. On the desktop, I use old.reddit.com, but for mobile, I use 3rd-party apps from the open-source F-Droid app store. I don't mind ads, I just like my user interface to enhance my workflow, not slow me down, track me, and actively annoy me.
