As we've noted a few times now, however bad the recent Facebook and Cambridge Analytica scandal was, the nation's broadband providers have routinely been engaged in much worse behavior for decades. Yes, the Cambridge and Facebook scandal was bad (especially Facebook threatening to sue news outlets that exposed it), but the behavior they were engaging in is the norm, not the exception. And watching people quit Facebook while still using a stock cellphone (which lets carriers track your every online whim and offline movement) was arguably comedic.

As the recent Securus and LocationSmart scandal highlights, wireless carriers pretty routinely sell your location data to a laundry list of companies, governments, and organizations with only fleeting oversight. And while some lawmakers are pressuring the FCC to more closely investigate the scandal (which resulted in the exposure of wireless location data of some 200 million users in the U.S. and Canada), few expect the same FCC that just killed net neutrality to actually do anything about it.
