Frankly, I don't think so, and that's probably the problem.
I could be wrong but most companies management that got a baked CMS think they got the most powerful, frikking awesome, and it general it's just a soup of unmanageable legacy code.
Of course there is a lot of other problems that could spring like a bad sales teams, but if the platform awesome ido not see why it should not be striving since it has been online for so long.
