I agree.

Reasons I can think of straight away (from listening to the reasons that  
such people have given for such decisions in the past) include:

Better control of look and feel
Better performance
Better integration with existing work patterns
The developer just wants to do it that way
More easily adaptable

Personally I find only one of these convincing. But I'm not the decision  
maker, and I see others being convinced to do things that seem to me  
completely and utterly wrong, like choose a heavyweight and complicated  
technology, every day. My personal candidate for most common example is  
getting a simple piece of text as a word document or PDF attached to an  
email, which among other things highlights that different people have  
different work styles and environments, which lead to different priorities  
and therefore different technical decisions.

Why would you believe for a moment that nobody would make such a decision?
