As mentioned by Rob Pardo in interviews, piracy is a serious problem and often times tie in closely with LAN. At the end of the day, we want the best for the community and fans that support our games, and having chunk of the community pirate the game actually hurts the community.
1) Pirated servers splinter the community instead of consolidating all players who love to play the game. Battle.net will bring players together in skirmishes, ladder play, custom games, and allow everyone the opportunity to share a common experience.
2) More people on Battle.net means more even more resources devoted to evolving this online platform to cater to further community building and new ways to enjoy the game online. World of Warcraft is a great example of a game that has evolved beyond anyone's imagination since their Day 1 and will continue to do so to better the player experience for as long as players support the title. The original StarCraft is an even better example of how 11 years later, players still love and play this title, and we will continue to support and evolve it with patches.
We would not take out LAN if we did not feel we could offer players something better.
If I were to buy StarCraft II or any other title, I know the money I spent would be going to supporting that title. Personally, I would be upset that others were freeloading while others are legitimately supporting a title that has great potential and goals of making this title have 'long legs.'
If you like a song a lot, buy it, and that artist will only come out with more awesome songs for you. If you like a game, buy it, and we will promise to constantly work to make the player experience better at every corner we can.
