The iOS limitations are a given, we don’t need to discuss them.

Joplin, as an example, allows syncing via WebDAV. Which you can easily self host.

I know that Joplin works differently. Obsidian also has integrated sync capabilities, but it’s a proprietary protocol and you can’t self host it. And I guess this is a design decision of the authors. To sell their service. They probably need some money to pay their bills.

It is proprietary? I mean the code is but I have no idea if the protocol is. Obsidian is a note taking app that saves to a folder. Any OS it runs on can use any syncing solution (as long as the OS supports access to those folders)
