John Legere is the CEO of a multinational telecommunications company. Of course he knows what the EFF is.<p>At first, he was just trying to explain BingeOn to T-Mobile customers in a favorable way - &quot;optimization for mobile devices to stretch the data available on your plan.&quot; And that&#x27;s exactly what an informed consumer should expect him to say. You&#x27;re not going to hear the words &quot;reduced quality by default&quot; or &quot;sweetheart deals with content providers&quot; come from the mouth of a man with fiduciary duty to T-Mobile.<p>But trying to discredit the EFF will blow up in his face. If auto company execs feigned ignorance about Consumer Reports and Kelley Blue Book, we&#x27;d laugh at them. It&#x27;s a transparent way to avoid answering the questions these consumer watchdog groups raise.
