Phill spoke a bit about this a couple months ago. The money is great up front, but it’s not great for long-term sustainability. There are a few apps where I have lifetime subscriptions (or was “grandfathered” in), and I definitely feel a little guilt that they’re essentially stuck providing support / features to me and everyone else in my position many years later.
I miss the days of simply buying my software and owning it, but the landscape is different now. Technology moves quickly, people’s expectations are much higher, everything costs so much more. Everyone has subscription fatigue, but you can flip that on its head by deeply considering what you subscribe to and what/who you want to support now and into the future. “Vote with your dollar”, as the saying goes, rather than just throwing your money at giant corporations, cable companies, etc.
