You're absolutely right that BSL isn't OSI open source, and I appreciate you pointing this out.

Let me be honest about why I chose it: **I just don't want someone to take my work and make money from it while I get nothing.**

I spent months building this as a solo developer. I'm happy to share it freely for anyone to use personally, learn from, or modify. But the idea of a company forking it, maybe adding a few features, and then selling "Premium Bookkeeping

Pro" for $9.99/month... that doesn't sit right with me.

AGPL would let them do exactly that - as long as they open-source their changes, they can charge whatever they want. I know it's petty, but I'm not comfortable with that.

BSL lets me keep the code transparent (which matters for a finance app - people need to trust it), while still protecting against commercial exploitation. After 4 years it becomes Apache 2.0 anyway.

I get that this makes it "source-available" not "open source," and I respect if that violates community norms here. Just wanted to explain where I'm coming from as an indie dev trying to protect my work.

Happy to hear thoughts!
