Great - Bluesky is much more appropriate for anything involving science, empiricism or rationality.

I know this is all probably amplified by recent political developments but as I have mentioned in few threads during the year, this shift for non-US public orgs has already started. The thing is that Twitter is no longer properly/predictably accessible to people without account - that is most people on the internet. So there is no point for posting on such sites if you are public organization. There could be critical mass of users on the site but anyone can open link to public accessible stream on Mastodon and BlueSky (at least for now).

There’s no way they change that; it was an essential part of what made Twitter useful, and important.

Same same.

Unless bluesky can work with noscript/basic (x)html browsers (including account creation) or has a stable and simple API?

Your requirements are potentially not that of ~29M current users (as of this comment). Network effects and all that jazz.

And they are jailed in big tech software(geeko|blink/webkit/c++ compilers)/protocols because they don't know/don't care.

X/bluesky, technically same same. Just the censorship is different because made by differently opionated people.

My only use case for this thing would be as a notification/announcement place from some people/organizations I would be interested in, who/which don't have a message board with a DNS name.

For X, nitter was more than enough for me before they forced people to log in to read the notifications and announcements and broke nitter (anonymous reader).
