I´m not sure VISA cares about business models - if you can do recurrings without chargebacks, then why should they care? If they want to mess with us, then they will do as before - just lower the chargeback rates, and then sit back and watch how the industry will adapt...
The other regulations they have made have been to protect their brand, and eliminate the loopholes in their security/fraud systems.
I´m sure VISA see the past regulations as great successes - now they have more control than ever, and I´m sure the overall problem with chargebacks are on a decrease.
VISA and merchant banks are in our industry to make money, and as long as they make high profit money with limited risk then they will continue to be here (due to our high risk status, then they charge more, than "normal" merchant).
On a per transaction basis, then adult processing is a lucrative "niche" for VISA and merchant banks....
