Attention, attention please: parent here again. Thank you all for the upvotes. I was, however, wrong! Thank heavens! I got in touch with the media contact, and he reports that the wording indeed means Verizon is no longer allowed to UIDH 3rd party sites.

I'm very glad to be wrong here. :) Thank you all for your support, and I'm sorry to have spread misinformation so far; it was not my intent!
