They could still do it even now. They don't want to do it. I could have data blocked on my XV6900. It could be done on any of the old Treos and the Centro. A host of smartphones which Verizon sold in the past. I remember the emails we would get when I worked there about all the revenue the company was losing due to data and text blocks on customer accounts. The alerts which would pop up when a customer had a block reminding me to try to talk them into removing it. This policy is all about the bottom line. Who buys a smartphone and blocks data? Lots of people. Not anymore though. Not anymore.
