The only suprise here is that anybody is suprised.
Adobe has never marketed CF in a positive light since the acquisition of Macromedia. Criminy, you can't even find it on the Adobe home page. So, after all these years, what on earth makes you think they are going to start now?
As for the deprication of CF features in Dreamweaver, I think many are making the false assumption that the DW team even realizes that Adobe makes CF. Do you see any evidence that the two teams even talk to each other? Do you have reason to believe that they even speak the same language since the deportation of the CF product team overseas? Did you really expect more from a company with the track record or Adobe?
As for cost being the biggest obstacle to adoption, if Adobe has not realized that by now, they are never going to. They are simply not that smart. They fail to realize that cutting the entry cost in half would likely raise the adoption rate by four-fold. Other complanies have proven this theory consistently for years. Not Adobe.There are "free" platforms that emulate CF, yet Adobe thinks they can keep selling CF at crazy prices with no marketing effort whatsoever.
Did you really put a whole lot of faith into the rumor that Adobe is already working on the next couple versions of CF? What would you ever expect them to say? Heck, here at work I am "working" on the next couple versions of every project I am on. Every time a customer mentions a feature they would like to see it goes into a list of considerations. Therefore I am "working" on the next couple versions.
Is CF a great technology? Yep. Has it earned me a living for close to two decades? Yep. Do I have an ounce of faith that Adobe is going to turn this ship around? I think you know the answer.
After a while you need to be more suprised at your high expectations and less suprised at the recurrent Adobe ineptitude. Take some personal responsibility and go learn another platform. Relying on Adobe as your career safety net is ignorant, and the time to learn something new is BEFORE you need it, not after.
