People keep using BlueSky and decentralized in the same sentence. That's literally not a thing currently unless you're connected to Fediverse through BridgyFed.
"But there's PDS that aren't hosted by BlueSky!"
And let me ask, where ELSE can the data from that PDS go? Nowhere? Then it's not decentralized.
BlueSky has 1 website. BlueSky.
Fediverse has 20,000+ websites.
The only way BlueSky is currently decentralized, is through BridgyFed by opting in. It's not decentralized by design like Fedi.
