"I would have expected more concern" From the public? Everyone carries a phone, pretty much everyone is on Facebook. Given a yes/no box to tick you're going to get a lot of "yes" to "do you think you should have freedom from being tracked", but given a choice of what hardware/software to use people are going to pick the ones which everyone else is using, so that they can contact them. Next to nobody is going to stop at 4g because 5g has a higher granularity of location awareness.
