Is the problem BlackBerry's or BlackBerry Mobile's?
I would not be so quick to assume that the software company BlackBerry is to blame. The hardware company BlackBerry Mobile who builds and also releases software updates is the one you have to "blame". ;)
With them taking on the DTEK's and releasing a new KEYone variant each month, and working on those two new phones... they have their hands full. I expect the number of CDMA devices in operation... puts them at the bottom of the list of things to do each month.
