I feel like some qualification is in order. I can't make any excuses for SOAP (maybe someone else wants to take that up), but COM, at its core, is indeed a simple and dare I even say elegant technology. COM is alive and well on Windows, because it still serves a basic need (cross-language binary interop) and it does so well.

The problem is that COM just couldn't stay simple -- the basic idea of querying an object for reference-counted interfaces was quickly buried under incomprehensible layers of pUnkOuter and IMoniker and apartment states and OLE activation sites and god knows what other stuff that you have to know about but doesn't help you getting work done.

I've seen people who can get carried away adding layers of stuff to something simple and beautiful without ever realizing that it stopped being simple and beautiful quite a while ago, because they still understand everything. Boiling frog design, if you will. I don't know Don Box well enough to tell if he's one of those people, but COM and related technologies seem to have seen a lot of that crowd.

It appears he was of that crowd:
