Is it a deal breaker for you that the app isn't open source? What if I create binaries for FreeBSD/your distro and there's no telemetry/option to disable connecting to the internet (even for updates)?
But usually developers don't care enough about the tiny userbase of FreeBSD to even consider that. If you would do that, I would really like it, though I can imagine that from a time/gains perspective there is no point. Which I do totally understand.
One thing I like is that your monthly fee is very reasonable. Obsidian costs double the price of my entire Microsoft 365 subscription :) Besides it being electron that's another issue for me. Especially because it's just not really that great.
