Again, I don't disagree, but the 65+ geographic will die off soon enough and they're unlikely to leave the game they love before they do, no matter what. The older generation is the most committed. They'll continue to watch every game and they'll complain through it and talk about how this isn't the way it should be, but they'll still be there. Because they love it.
And when they die off, if MLB doesn't attract new fans and at a good rate the sport will begin to flounder. And you can talk about how stupid/or not stupid young people are (this isn't the point of my post, not by a long shot), but the point is that we are as a society moving towards more instant gratification. It's a serious psychological problem. There are numerous studies available that show that younger people are having diminished concentration levels. Many won't sit and watch clips over 30/40 seconds because it takes too much time. Anything above 280 character is deemed too much to read. That's where we're at.
In the UK, cricket at its peak was played over five days. It was considered the highest form of the game where only the most skilled could live. Now the highest and most paid form by a massive amount is 20/20 where a team comes in and thrashes the ball around for as many runs as quickly as possible before the other team comes in and tries to hit more. It has completely changed the face of the game. Whereas the old style of the game used to have grounds mostly half-full with older people (mostly men) the new form of the game has stadiums filled with kids and families and the money being generated is incomparable.
MLB is fighting for it's new generation of fans. I'm not saying what they are doing is right, but I certainly understand why they're doing it. Although, they should have been honest about it up front.
