I don't think that was my impression, but their API is pretty open for creating plugins. In support of the Obsidian model, its a dedicated engineering team, a free tool, notes are stored as .md and not something proprietary, and if you want you can pay them for their sync tool which I find both pretty reasonable and a nice way to support their efforts. Also they keep on improving the product in interesting ways, the new plugin marketplace with all of its verification policies is really nicely done, aspirational even.

But in any case, this is also a nice project, but I guess I'm also an Obsidian evangelist.
