What is with MLB.TV

Why do I get commercials when I have subscribed to MLB.TV Premium?
This is crazy.  I subscribe to a service and they are throwing commercials at me.  Not just when I login to watch the games, but whenever I switch between games, I get the commercial.

I am sure tired of watching some guy and deer fight.

This is stupid.  When I get pay-per-view, On Demand, or other premium service I never get ads.

Major League Baseball needs to get out of the NFL attitude of bilking the people who pay their bills and they only reason these games exist, their fans.

Get a clue and when I pay for something, I should not and must not be subjected to ads.
