I’m not sure if this is new, but when I clicked on the /r/pics protest post link from the frontpage here, I was redirected to this: https://old.reddit.com/premium
I’m not sure if this is well-known or not that they’re pushing it now, but it’s the first time I’ve seen it, especially on old.reddit.
It wouldn’t necessarily be a win for 3rd party apps because it still raises the cost to use them. $9 for Reddit is quite the ask already. 3rd party devs would need payment too and frankly social media ain’t worth anything over $5 to me
