I do, I think it's absolutely stupid because it implies that every page follows the same basic notion of fetching content from the DB - except that in any serious system, you don't have that finely grained workflow, you just need to bootstrap, authenticate a user, then divert the controller to the relevant part of the system.
WP's model misses the fundamental basis of MVC (or indeed, anything approaching an extensible system that separates logic and presentation) at the cost of making it nicer for simpler uses and customisation. For what I was doing 3 years ago, WP was acceptable. For the sorts of things I might want to do, WP is essentially a toy rather than a serious foundation I'd want to go near.
