Hm, @logseq requires a contributors license agreement (CLA #cla ) to sign over all contributor's code to the company, so does the @joplinapp, with @joplinapp also having the server component source-available.

@obsidian is closed-source, wants $50/yr for a commercial license, paired with their $10/mo for sync - that's a lot of dollars for note taking.

Alternatives, anyone? Ideally open source to which I can contribute financially, without a CLA that will inevitably mean a change in licensing.
