Of all the things wrong with the game, this isn't the one I'd look at. 
In the stadium, blowouts can be fun when the home team's ahead.  Even when losing, I paid for nine innings of baseball.
On TV, blowouts can make for very entertaining viewing depending on the broadcast team.  A laugher will still bring better ratings for the RSN than any other crap programming they have.
From a fantasy perspective, it's outrageous.  After opener pitchers and the death of the SB, there's only so much of this I can take.
