While you have a small point with this - check the history of the terminology behind "OLAP, OLTP, Cubes and Warehouses" before you spout in this particular topic..
Part of the reason for the 'new terms' (which IIRC are roughly 15 years old) is because of different lineage (Cubes did not oringally get stored in a relational database) and a need to differentiate the design methods (OLTP applications and OLAP applications have basic design differences in order to meet business requirements.)

Now you can "do everything on a conventional database". 5 years ago was a different story.

Which is a credit to some fairly serious skull sweat that's gone into consolidating the different technologies.

Now you are getting to the meat of your email! I get the feeling your issue really is that some management styles (some specific managers) that reinforce the reality of Peter's Principle. Incompetence has it's own rewards.

I think the marketeers are doing what they are paid to do. So are the sales guys. Doesn't mean I have to like their style or tactics. However, those styles and tactics can yield great rewards - just look at good ol' Microsoft (amongst others). And just like Pavlov, the industry keeps rewarding and reinforcing some specific behaviours. C'est la vie!

As someone once said "You always have a choice. If you don't like it, you can choose to leave"
