> I plan to continue its development regardless of revenue

I would respectfully suggest that this can be understood by some as a promise, and I think it is not a promise anyone should make. Doing things for free is not sustainable. We all need to earn a living, that's how our current societies are built. So I really hope you will get enough subscribers at reasonable price points to make this sustainable.

You’re right, there’s nothing more certain than money. I aim to generate enough revenue to develop Strflow full-time. Thank you for your support!
