I see a lot of posts like these, and I'm left to wonder: is the issue the subscription model - which I know a lot of people aren't fans of - or the value proposition of C3 with a subscription model? While I'm not especially thrilled with subscriptions, it's a fact of life these days, and my issue mostly lies with the lack of a compelling reason to subscribe to C3, which still just seems like a port of the C2 IDE to the browser with some very minor updates, and that's an issue when asking for more money, more regularly.
For me it's the former. I find it very hard to stomach software subscriptions. Autodesk Maya goes subscription? Fine, I'll use Blender instead. Adobe Photoshop? No prob, Gimp serves me just as well. C3, well... The new workflow improvements look nice, but C2 is already pretty solid in that regard. And C3 doesn't address my main concerns about C2 either, namely performance and portability, so yeah. I would have gladly forked out twice the price of C2 if a one-time payment option was on the table, as C2 has been a real boon for me. But subscription, nah.
Software subscriptions are not a fact of life I'm willing to just lie down and accept, and certainly not in the world of gamedev middleware where alternatives are all around.
