There are algorithms working in the background on Reddit to keep you there. Same with pretty much all “social media”. They aren’t on Lemmy. The point of Reddit is to keep you there, and shove as many ads down your throat as possible. Ads don’t exist here, and no one (as far as i can tell) is making money from you being here.

Honestly, I’m in agreement with OP. Yes it’s going to be/is a “famous” photo, but I join subs like this to NOT see all the depressing political/end of world/consumerism crap.
