But what about the DIDs, the things used to actually identify accounts within the ATproto ecosystem:

But Bluesky has developed its own DID method, did:plc. Today, did:plc stands for "Public Ledger of Credentials", however it originally stood for "Placeholder DIDs", with the hope of replacing them with something else later. The way that did:plc works is that Bluesky hosts a web service from which one can register, retrieve, and rotate keys (and other associated DID document information). However, this ledger is centrally controlled by Bluesky.

It's literally not possible to have a functional PDS without registering with a Bluesky server and they maintain indefinite control over the ledger. All your data is tied to this DID, it's how the entire protocol is designed to identify stuff, how decentralised is your data if it's dependent on Blusky (the company) assigning you an identity?

This is false, they support did:web which ties your identity to ownership of a DNS name (which is its own can of worms, but not controlled by bluesky like PLC).

Unless you mean that you still have to register your pds it to get indexed by the relay, so people can read your posts without querying your server directly (which is possible but discouraged). This is actually an advantage over mastodon/activitypub however, your personal pds will not crash if a post goes viral (unlike a personal mastodon instance).

I spent a couple hours trying to create an account on pds.flamingos-cant.xyz that uses a did:web following the instructions here and the account at the end ended up with a did:plc, so IDK how you create a PDS with a did:web but it's clearly not something they put a lot of effort into supporting.

i forgot the DIDs
Oh no

They support did:web too if you don't like did:plc
