Absolutely true, and I agree 100%
that's what you're doing when you use Negative Option billing, even if you provide all the disclosure in the world up front
Here's where you go off the rails a bit. It's entirely possible that companies have tested and they know that requiring users to take two explicit actions (free-trial signup & entering payment details) instead of just getting it all done at once will result in a lower conversion rate. That's just human nature, and I'm not sure that acknowledging it is "consumer unfriendly".
The main problem I have with your logic is that it makes the very concept of subscription services "consumer unfriendly". Why rebill customers every month for anything? They should really have to come back to your site and take an explicit option that they want to keep paying for and using the service in question.
so does Apple (for Me.com)...
etc. etc.
In addition they also offer FREE plans for their services - which require no CC at sign-up and allow you to upgrade at any time.
Edit: Any comments on the downvotes would be helpful as I was just trying to supply more detailed information on the actual process being discussed.
