That’s not the same thing, that’s a paid subscription model. Social Media websites make money by getting rights to share your data, and in return you get to use their platform for free. Every time you see an advertisement or promotion it’s because Twitter/Facebook/Reddit sold your data off to Advertisers.

You don’t know how these companies work. They couldn’t pay to host the servers to keep the datacenters running if they couldn’t republish data for profit. It’s an integral part of the business.
