I happily pay for software. ONCE. I have no idea if this software will be regularly updated and if there will be new features. How do we know the developer won’t abandon the project? And it’s a lone developer, apparently. Ever heard of the bus factor? Give me a license that enables me to use the product in its current form indefinitely, and I might consider buying it. But a subscription? No thanks. Who does this guy think he is, frickin Adobe?
