It's really shitty to have purchased an app a few months ago only to have an automatic update happen, and the app switched to a subscription model. No, I'm not paying a subscription fee for an application I've already purchased. Fuck you.
This shit has happened a lot lately is why I lean heavily toward FOSS these days. Let's call subscription-based software what it is: rentalware. I don't care that the market is moving to it. It's still wrong.
