As I mentioned above, I don't feel strongly about Bluesky winning, I just don't like misinformation. (I also have other things I care about more that take up what little free time I have for tech stuff already, so I'm not going to undertake something major just to prove a point.) If there's really a fundamental problem with AT Proto and how it can be used, Doctorow's post should have made that explicit.

I did find a (more recent) post that goes into detail about what's lacking, and I've edited my original post accordingly.
