This is kind of problematic indeed. On one hand, it sounds reasonably "fair" for everyone involved. It seems that T-Mo is committed to impartiality (the site repeatedly mentions that all legal music services are eligible). They aren't double-dipping, since it's on top of the metered bandwidth you paid for (as opposed to charging the user for unlimited/unmetered data and then throttling services that don't pay up). On the other hand, it's terribly opaque. Are they charging the streaming providers? Do the providers need to install dedicated proxies for T-Mo customers? Are they charging everyone the same? Is every service on the same terms? It's quite obvious that they have a cross-promotion deal with Rhapsody, but does Rhapsody get preferential treatment? It seems that T-Mo are aiming for a compromise in regards to net neutrality. It doesn't seem too bad at this point, but there's always the risk of a slippery slope.
