Try and see it from another angle, when the game sped up the more views the game got and the more money came in, so why wouldn't he try and speed up the game? Its great for business and the people who are streaming the game are willing to pay more money to continue stream it.
Do I think the game is a little to fast, yes of course and I think last year was the best the rules had ever been and it was played at a great pace.
PVL is not killing the game he is growing it, he and his team have made this game so much bigger than it has been in a very long time and there are definitely going to be times where he goes to far like now and thats okay as long as they take on the data and learn from it. For someone in his position the game is bigger than the players.
Also what's to say the PVL is the one deciding to make the game faster, maybe its those who are putting money into it (i doubt it but tin Foil hat stuff you know)
