You, as a user, should not care one ounce of what's inside your addons and what they are using. All you should care about is that they do what you want and that they do it well.
For crying out loud - the way some people talk (and I'm not really directing this at you or anything, Tango2k7) it's like Ace2 was some sort of religion that's going through some sort of schism and they now need to pick a side or perish. STOP FREAKING OUT!!!! Calm down, take life as it comes, and deal with what you get. If you can't handle it, then find something else.
I think if you substituted the word BRAND for the word RELIGION you would have a better picture of where the average END USER is coming from.
ACE has become a BRAND to some extent and although most end users are not savvy enough to really understand the difference between framework and libraries when it come to coding, they do recognize that when their BRAND is being switched.
I mean ... after all Coffee is Coffee right? So don't mind me as I switch you from Starbucks to some other brand, regardless of whether that brand is actually better or even has virtually the same coffee inside.
Get the point now? You guys made a BRAND out of ACE ... and now you are going to face BRAND AWARENESS issues. You can't sweep that under the rug, and ignoring the "split" is not going to work as well.
And FWIW ... last time I checked Linus Torvalds was in sole control of what gets added to the Linux Kernel and that OS is a phenomenal success story. Not really sure why all you programmers can't just let CKK be the Linus Torvalds of ACE. Seems he did a pretty good job getting it this far.
Oh .. cause all of you are better programmers ... got it ... my bad.
