The mobile providers use public spectrum that they license from governments.
Make it a condition of the license that they are only allowed to provide dumb pipes and PTSN services. It will reduce the value of the licenses, but not by much, because this is a service that they haven't introduced until now, so was not priced in to the original auctions.
Note that while using VPNs will assist, the telcos have your IMEI/PSTN numbers and assign the underlying IP connection (whether CGNAT or otherwise). So they can track the traffic at the L2/L3 level.
Then they can introduce a "merchant's service" that takes that traffic and maps it to an identifier that's provided to the websites/advertisers. Even if the L4 traffic is encrypted, the packets themselves could be extended to include the information they need before it exits their network.
But all they see is your IP connecting to the VPN IP. And the connection between the VPN and the site has a new IP connection, doesn't the VPN just send L4 data + its own user-ID?
