There is a large company I used to work for that we all use everyday and most of their services are free, but before I left they were discussing using credit cards as a means to defend against abuse in a free service. (The specific service being discussed hasn't been released yet) While it would cut back greatly on abuse, it'd probably significantly reduce adoption. I was always against the move... but in the start up I'm working on now, I feel it'd be more convenient for both sides to just take care of the credit card stuff up front. The big difference, to me at least, is that what I'm working on is a paid service.
