I am a T-Mobile customer. And when they first introduced Binge On I was mostly happy (Net Neutrality notwithstanding): seemed like a fair trade, for certain sites you lost video bandwidth but in return received unlimited streaming.
However T-Mobile's implementation is bad and worse still they weren't honest about what Binge On does. It is a completely different arrangement between ONLY limiting sites that signed up, and interfering in third parties who did not, and don't even get me started on limiting video file download rates (i.e. not streaming).
The CEO is just acting like an idiot. Consumer rights groups, like the EFF, are completely entitled to "stir things up" when large national corporations start acting poorly. If you guys didn't want to be called out, perhaps you could have been more honest to begin with? So as a T-Mobile customer, I am 100% behind EFF on this one. If they started attacking the EFF regularly I'll change networks (e.g. Project Fi), because I value the EFF more than T-Mobile.
PS - Amazon's Smile.Amazon.com supports EFF donations, as an aside.
