partially because you're presumably paying for the amazon service, but not necessarily with an open source project. one of the ways some people 'pay' for using an OS project is by helping in forums/docs/etc. presumably, the money you're paying for amazon services is/should be going in to their documentation.

also... with an OS project, I can actually get the code and see how it runs, test patches, etc. I can't actually do that with their services, and any docs I might contribute would be guesstimates as to how things actually work, vs how it actually does work (and what's intended), which would/should come from the company that actually owns the code in question.
