I've since calmed down from the initial sticker shock of C3, but still maintain it signals the end of Construct. Here's the issue:
Hobbyists - will pay for one year (maybe two) on a subscription basis. The novelty of making "apps for fun" wears off quickly for most.
Dev - At $149 per year for the right to monetize apps, it's a tough sell. The app market is about dead for 90% of indie developers and Google Play constantly sends out bots for issues such as outdated Cordova plug-ins etc. They also constantly change their terms for monetization and as a dev, I don't want to be beholden to keeping a C3 license just to possible "fix" apps that are flagged on GP in the future. $12 a month just to use C3 is too much. Most "new devs" (Constuct level) will never see $12 a month. My latest app created with Android Studio made 2c today - that's right 2c. It's not as easy as many think.
The beauty of C2 was that you already owned the license, so any issues could be worked out "eventually'. It's a shame becasue despite my criticism of C3, I had a lot of fun with C2.
I don't remember the same defensiveness of C2 as there is for C3, in itself, that's an indicator to me that the subscription platform may be being realized as a mistake.
