No, google did not move the goal posts.<p>There were, in fact, at the time, various 3rd party YouTube apps that worked perfectly well and were completely within the scope of the TOS - I personally preferred Jasmine on iOS to the official client.<p>Microsoft, however, decided that they were a special snowflake and didn&#x27;t need to play by the rules. In fact, they also removed ads from YouTube -- Google&#x27;s source of income with respect to YouTube.<p>Google was no doubt snipping WP. But Microsoft was in the wrong on that one - which just made it easier for Google. And the reason MS didn&#x27;t want to do an HTML5 client for WP (and didn&#x27;t want to admit it either) was that the HTML5 implementation on WP was not good enough to run YouTube reasonably. So they put themselves in the spot of either admitting an inferior browser or violating TOS. Either way, they made it easy for Google to hurt them.
