You can use keepassXC and "self-host" your passwords on any cloud-storage you want (it's just a file after all), but if you are using 1Pass at the moment, I don't see an opt-in anonymized telemetry system as a reason to switch.

What you are alluding to is called "DIDs" = "Decentralized identifiers" (see https://en.wikipedia.org/wiki/Decentralized_identifier).
The idea of most of these methods is that you identify yourself using a private key, while a public key is spread throughout the network.
If you want to log into a server on that network, the server would "challenge" your identity by encrypting something (e.g. a random number) using the public key, which you, the holder of the private key, can then decrypt and send back to prove you are who you say you are.

This method is already standardized by the W3C, but only has been for less than a year. You also have to keep in mind that all federalized social network systems (such as lemmy and kbin) are still in early development.

I really like patreon since it allows creators some independence on the whims of platforms and advertising companies.
It also allows certain content that doesn't (currently) work on e.g. youtube to exist: E.g. (very) long form videos or highly produced documentaries that may take half a year to plan and shoot just cannot exist within youtube due to the limited per-click revenue.

That doesn't mean this system is perfect: E.g. I would like to have an option to put some money into a monthly pot, which gets distributed based on my viewing habits and current interests. E.g. Twitch has "bits" which can be bought in bulk and distributed freely as donations.
Having a monthly system for "tokens" according to which a monthly donation gets divided into (i.e. a person got 25% of my tokens, so he gets 25% of the pot) would be nice (this does have the potential issue of hurting long-form content, but I could still donate the normal way).
