I wouldn't go quite that far, but I do agree with a few of those points:
The speakers can be blaringly loud. It depends a lot on where you are sitting with respect to the speaker positions, but I have one directly above my seats and it occasionally becomes very distracting and drowns out any attempt at conversation.
I wish the video board would be utilized more often for replays, as that is where I find the most benefit.
I do miss the traditional organ music and would much prefer that over the personalized player walk-up songs (most of which have zero appeal to me), but I also completely understand that the world has moved on and the walk-up music is never going away.
With that said, I think the game experience is largely the same as it has always been. You might have to put up with a few more advertisements and you might have to go to the concession stand instead of waiting for a hot dog or peanut vendor to walk by, but the cumulative changes that have been made are relatively minor in the grand scheme of things.
