> If I am fully self-hosting the entire bluesky app, I need to spend ten thousands of dollars a month, but it'll keep working.
That strikes me as a point in favor of AtProto for decentralization (unless it's possible for others to cheaply/simply run their own backups of the entire mastodon.social instance & I'm just unaware of that fact).
> With bluesky it's different.
The key AtProto differentiator I find most compelling (which it seems you omitted from your list) is that Bluesky can disappear tomorrow and, if I'm running my own PDS, I can simply log in to another different platform using my same username & account and immediately see my entire message history w/o skipping a beat.
From the standpoint of an individual user who just wants to own their own data w/o needing to worry about hosting entire apps or manage scaling, the fact that AtProto allows me to host a PDS and do just that while still using any of big-name apps w/o needing to create new logins and fracture my online presence feels like a far more pragmatic trade-off, IMO.
I guess it comes down whether you care more about data decentralization, or platform decentralization. Personally, I care far more about the former, and to that end the AtProto model feels much easier to set up & far more seamless in practice.
