Yes, but who said otherwise then?

Oh OP made it up. Nvm. They write themselves that it is a notion alternative.

None of those tools are editors, right? They all try to be a notion alternative, which is also not an editor. There is basically 0 focus on typesetting.

No, because with the above you can have rich objects in databases (for example, a dynamically updated list of medical events, each with all the attributes I want, attachments etc.), and almost arbitrarily deep nesting of databases. The idea to have databases with pages is one of the key features that made notion successful. It allows to structure knowledge without duplication, in addition to provide some other no-code features.

Spreadsheets are not even close.

Open source analytics tools are still pushing for ad-driven business models that make the world (and the content) worse. Open source LLMs still waste computational power and pollute. And the list continues. Some open source technologies serve a good goal, some contribute to make the world as bad as some non-OSS.

The other user already shared some article with lots of historical data, both words and actions, that should give a better picture. Anyway, since you decided to ignore all that, then there is also to say that the tweet was a speculation made months ago on a topic where nothing happened yet (or at least, I haven’t read any news about antitrust in the last month). I don’t think anything will happen, but anyway that makes it at most naive.
