Some us based companies forbid to use obsidian due to this clause in license:

This Agreement shall be governed by the laws of the Province of Ontario and the laws of Canada applicable in that Province. Any action or proceeding arising from or relating to this Agreement may only be brought in the courts located in Kitchener, Ontario and each party irrevocably submits to such exclusive jurisdiction and venue.

I don't want to have to separate my notes between work and personal. Sometimes in my daily journal I will think about work things. That would requires me to pay $50 a year for an editor to edit Markdown files. That seems steep even if mostly I use it for personal use.

A solution springs to mind, but I fear it would be impolite to state it directly.

Well my solution is to use an editor that is free, open source, and is not burdened by a license that cares not what information I store in it's memory nor how many other people I organize with.

I agree. This is my solution also.

Obsidian's license terms are weirder than expected. But I'd never hesitate to use a Personal license for random, incidental professional purposes.

But I'm much happier to avoid thinking about the question altogether.
