The Federal Communications Commission (FCC) reiterated its stance on 'Do Not Track' requests last week in response to a petition by advocacy group Consumer Watchdog. That is to say, it supports regulation of privacy practices for Internet service providers, but not for websites, apps, or anything else.
The petition requested 'edge providers' such as Google, Facebook, Netflix, and so on honor Do Not Track requests from browsers. When honored now (rarely, given it's optional and tends to hurt revenue), the sites and services in question do not collect potentially very valuable and arguably intrusive browsing data.
In response, the FCC dismissed the petition, noting the request is "inconsistent with the Commission's [...] scope of the privacy practices it states that it intends to address."
