They are decentralized, the architecture is just more complicated and harder to run, but they are in fact decentralized.

You can run your own pds(data host), relay (pulls data from all pds), app view (app frontend), moderation (still in progress albeit), and even algorithms.

We have to stop saying they aren’t decentralized just because it’s more complicated and restrictive, large social media platforms will inherently be complicated and expensive in order to be reliant and fast.
