What are the most important “points of control” that, in the case of Bluesky, are in the hands of this one company, and in the case of Mastodon (or the Fediverse at large?), are in the hands of the community?
It appears that on Bluesky, similar to Mastodon, you can start your own server by now. But on Bluesky you’re not (yet) able to have other users sign up to that server? And you can’t have your own moderation rules on your own server (yet)?
If I would start my own Bluesky server, and a friend does as well, would our ability to communicate be somehow still at the mercy of choices by the Bluesky company?
What is the practical difference between the AT protocol being controlled by a (public benefit) corporation, and it being controlled by a web standards body?
Disclaimer: I’m not a secret Bluesky fanboy. I just want to have the arguments ready to convince friends to not join Bluesky, and join Mastodon instead.
The way it is taught in many Earth Science text books, is that if you have two similar volumes of air, but the first is colder than the second, the first will have a higher density, and therefore a larger mass, and therefore a higher air pressure (e.g. at the surface).
Following this logic, you expect higher pressure in colder areas, as long as the volume of air (the height of the air column) is the same. I think the answer to my question has to do with the latter: the atmosphere is less thick at the poles. As a result, despite the much lower temperatures, the air pressure at the poles is generally lower than (for example) at the subtropical highs.
