I expect folks will like TV Everywhere. The question is always "compared to what." Unmentioned in the article is that cable operators generally include an "alternative media distribution" clause. Or, in other words, the largest cable ops can insist that TV Everywhere is the only means for distributing content available via cable online -- if one believes in cable market power.
As always, it's complex, messy and some sets of solutions will preclude others. The immediate question that grabs my interest is whether we should treat "over the top" distributors like Netflix and Hulu as covered by the statutes that prevent cable operators from denying programming to competing providers like DIRECTV. There is a near 100% overlap between broadband access providers and subscription television providers (that is to say, nearly all remaining broadband access providers also provide subscription television, not that all subscription television providers have broadband access -- although if you include resale agreements that set is pretty common). This creates a powerful incentive for existing MVPDs/broadband access providers to disadvantage "over the top" providers in the same way cable had an incentive to disadvantage DBS in the 1980s and early 1990s.
