I don't think clickteam doesn't care about their product - there's no proof of that that I've seen or heard of.
That said, I think pretty much every part of C2 is superior to MMF except for parts that aren't finished yet, like the image editor and such. There are a ton of advantages to C2 over MMF, and not many the other way around, and most, if not all of those advantages I've heard are on the to do list (EXE wrapper, improved mobile performance, easier object switching, etc). Stick with C2! :)
