&gt; What Tmobile is doing isn&#x27;t a challenge to the end.<p>Yes, it is a direct challenge to the free and open internet. It closes mobile internet towards a specific use (HD video) based on the decision of a third party who does not know if HD video is needed or desired. The high bitrate could be critical to the application in question (for example a medical video consultation, a collaborative image editing tool, or some as-yet un-invented use that may now never happen)<p>T-mobile could disrupt the mobile carrier market by pushing for open protocols by which the client or server can indicate that lower bitrate videos (or lower resolution images) are acceptable or preferred.<p>Not to mention the fact that each Carrier&#x2F;MVNO requiring a startup to implement their specific technical requirements to be eligible for Zero Rating has a direct, negative impact on competition.
