In my opinion, "accepted" is not the most precise word to describe it. If telco companies would say at the beginning: "You can buy mobile phone from us, but the part of the deal is that you will be tracked. Do you accept that?" If most people say Yes, that would be accepting it.
The reality was, that it was slowly revealed over time that the tracking is being done, and most people realized it only after mobile phones became a norm and very hard to get rid of.
