I don’t know what you mean here
I could understand an NDA if you’re talking about the particulars of the backend, but the fact that we don’t know what the NDA contains, AND the author of the entire protocol hasn’t been approached doesn’t bode well (https://octodon.social/@cwebber/110567421460454488)
Honestly I think the drama is a fundamental outgrowth of the way we think about a “feed”. The setup was devised to give people more reason to stay online exposed to advertising, in expense of an overall positive experience. But that’s sort speculation and I wouldn’t be able to point to specifics.
