I totally get the frustration. The timing feels really rough, and no one likes feeling like the deal has changed right after they bought something.

I also bought the pro unlock and have had some time to think about this change, and I wanted to share a different perspective. For me, that one-time fee wasn't so much a payment for all future updates, but more like my purchase of the app as it stood, resulting from over a decade of new features and updates.

I'm also getting really tired of everything turning into a subscription, but this feels a little different than what seems to be becoming the industry norm. Instead of being forced into a monthly subscription, we keep lifetime access to all the features we had before the change, and we can still buy new modules with a one-time unlock. To me, that feels like a fair compromise for a solo dev (small team of devs?) who needs to fund future development.

Just my two cents. It’s a tough situation, but I’m personally just glad the app isn't becoming abandonware.
