If there was a cloud hosting service that was totally free to host your web, app, database, etc and the only caveat was that you would allow the cloud host to be able to aggregate & mine all of your user/customer data for monetization, would you be willing to use such a service?
I'm hard pressed to identify doing anything that would destroy my business faster than this, aside from "cutting out the cloud hosting middleman and just tweeting the customer data directly."
