Officials are interested in what personal information ISPs collect, as well as how they do it and why. The regulators will also know who has access to the data, whether it is anonymised or the level of transparency. The FTC would also like to know if customers have control over their data, including options to shut down data collection or delete what ISP holds.
This will not necessarily lead to any breakdown of any of the companies involved. It can ensure that they fly right, but. And given that telecoms have sometimes played fast and loose with customers' privacy, it won't be quite shocking if the FTC tells them to change their practices and keep sensitive information from falling into the wrong hands.
