Why do I have a problem with Android market

I bought Samsung Galaxy S phone. It has Android in it and it is a wonderful phone. And then there is the Android market which has a lot of nice applications in it. The problem is that I don't trust them. I'm so used to use Free software that any proprietary code makes me suspicious.

And why should I trust? Android applications knows more than they should.


Where is a market place for Free software only?
I think FLOSS-market place could be a great way to support Free software. So far, I haven't paid for Free software (although I've donated), but I can see myself paying for Free applications more happily than proprietary ones.
