A new study conducted by research teams at Northeastern University and the University of Massachusetts Amherst at a conference this week, shows that U.S. wireless carriers not only regularly throttle video streaming post net neutrality — as many said they might do only to avoid congestion and bottlenecks — most of them are doing it pretty much all of the time everywhere.

From early 2018 to early 2019, AT&T was found to have throttled Netflix 70% of the time and Google’s YouTube service 74% of the time. AT&T apparently didn’t slow down Amazon’s Prime Video at all.

T-Mobile throttled Amazon Prime Video in about 51% of tests, but didn’t throttle Skype and barely touched Vimeo.

Verizon Communications, AT&T and T-Mobile have each acknowledged in the past that sacrifices in speed are required to deliver videos people want to watch.

Looks nice, efficiency of "free market" in all its beauty.
