Don't think FCC has anything to do with the blackouts. The NBA package is not affected. In fact, NBA games aren't blacked out in League Pass, even when the opponent network is the only one carrying a game. This is all about MLB. They have fans willing to pay (most are 'displaced, such as Yankees fans in Kentucky) and so there's no reason to change from MLB's perspective. Even though a black-out free MLB package would be great for promoting the game and would sell like (something less cliche than hotcakes).
I am in-market for Twins games, but bought mlb.tv yesterday, so I will be able to see the AL Central rivals, plus the Rockies and Dbacks (closet fan of both, even before Cuddyer and Kubel) and be able to hear Vin Scully all game. I paid $124.99 for premium. One improvement this year is premium buyers get the At Bat app, unlocked for mlb.tv, no blackout radio and GameDay graphics, included for no extra charge. Have it set up on my iPad and iTouch and worked great for yesterday's Yanks/Phils ST game. Last season, this app cost $14.99 and if you wanted it on more than one device, you had to pay that price for each device.
