Unless you were the person who works at Realmac, and personally performed the iOS 7 update, I'm not sure how you can possibly say something like this. I didn't do it either, so it might be that you're correct. The notion that asking someone to pay for your work is "screwing over your existing users", is exactly the problem that is being discussed. Personally I don't think that it's that strange to ask people to give you a few dollars so that it is worth your time to keep working on things for them. But hey that's just me. Your final point shows that you either didn't read the article, or you didn't read the first sentence that you wrote. If Realmac ups their prices because they are unhappy with the money they are making, then everyone (including you since you feel entitled to free upgrades for life) will just leave.
