<i>After that, they degrade services that are not paying them and zero-rate + allow higher bitrates for services that pay them.</i><p>&quot;degrade services that are not paying them&quot; and &quot;allow higher bitrates for services that pay them&quot; would even more blatantly violate FCC net neutrality in the US.<p>T-Mobile here is circumventing this by only zero-rating with an opt-out mechanism. If they tried to pull a stunt like Deutsche Telekom in Germany, they&#x27;d be fined in no time by the FCC in a clear and shut case. They are doing something far more subtle here in the US.<p>EDIT: For clarity, Deutsche Telekom is a majority shareholder of T-Mobile USA.
