> There is already a growing ecosystem of tools that are Obsidian-like

That very much depends on the definition of "like". Most are very different in their concepts and abilities or even foundation. They are mostly similar, if you compare it to cloud-tools, or old commercial tools.

I think this is fair, and maybe “Obsidian-compatible” would be a better way to describe it.

With that said, there are a few key tools that are extremely similar conceptually, e.g. Logseq/Roam. Logseq in particular feels like “Opinionated Obsidian”. And this is where most of the tooling growth has been occurring through plugins.
