Blizzard is doing what they think is best for their game, plain and simple. They could be lying through their teeth, or everything they've said is the truth. Sometimes I wonder why game companies try to defend their decisions every time a new group of people complain about a design decision. If you as a consumer don't like a design decision, don't purchase the game.
The fact of the matter is that internet connections are the new game requirement. Very soon they might become the only requirement if game streaming services manage to take a significant chunk of the market. For all the people out there who have shoddy internet connections and can't play the game because of it, maybe you should invest in a better internet connection. If I couldn't play a game because I needed a new graphics card, I'd go back to the store and either buy a new card or return the game. At the moment, you can't always get a better internet provider but sometimes you just have to wait.
I most likely won't be getting D3 not because of the internet requirement, but because I wasn't impressed by SC2, I haven't even finished it because it didn't hook me, and I worry that D3 will be very similar. I loved getting a new game, reading all the manuals and pages of history and then playing through the game to get the rich story. SC2 came with no detailed histories, no new insights. If I want to read game lore now, I just go to the wiki.
