To be clear: I prefer to pay for things instead of having to see ads but 13€ / month!? For a meta product that has inherently user-hostile design patterns even without ads?
Anyway I don't see myself ever paying for social media LMAO, and even less now that I know about the Fediverse... Seems like a VIP lounge for us if you ask me, and I'm okay with that.
On Meta, you pay so they don't use some of your data for showing you ads, while they collect tons more of data on you and sell it to the highest bidder.
On the Fediverse, you only give everyone access to all your published data for free to run whatever analysis they want on it... but at least you can choose from 1000+ different instances to pick the one that will be able to track your behavioral data.
