This morning when I opened Infinity to check Reddit, I saw the announcement above: they're going subscription-only. Ironically enough, I couldn't scroll down to see the rest of the message including prices, if there were any. I also couldn't see if there was a button to close the message or start a paid subscription. I couldn't proceed to Reddit at all. My only option was to close the app completely. So I uninstalled it.
That's it for me using Reddit on mobile! Can't say I'll miss it much. But I added a LOT of content to Reddit that way, so it's their loss. Fuck you, spez!
