This seems to be left out of the conversation when comparing Bluesky with the wider fediverse. The AT protocol relies on a bespoke setup and is complicated to implement. ActivityPub is comparatively simple, and can be implemented on pretty every thing with just a few endpoints.

There is not a bespoke setup that you need to implement atproto. In fact, there are already a variety of applications making use of it (some to a higher degree than others). There are community implementations of app views, relays, PLC directories, and PDSes already in the wild, and - although I admittedly have a biased ear on the conversation - developers tend to appreciate the _lack_ of complication when implementing things.

If ActivityPub is “simple” then that’s a recent’ish development. It used to be a mess.

I would imagine AT gets easier to use/setup given time too.

They said comparatively simple. As in, simple compared to AT

You can do a basic[0] AP server in a single small (64k) PHP file[1].

[0] Single user, admittedly, but if we're talking about protocol simplicity, that's the nub.
