As a minion for another gambling service, I was never terribly bothered by Blink's legitimate successes. I was only really bothered when CCP gave them rare items in secret, as if they knew it was a bad idea and really didn't want the community at large to find out. When the end was nigh, I can't say that I was particularly impressed with Somer's attitude, either, which seems to have been "if I can't monetize this, I'll just shut it down."
I never actually played there. I considered the house's take to be set excessively high (generally in excess of 30%). To my knowledge, Blink was one of the most expensive services in the EVE gambling industry. That said, plenty of my friends loved it and had a great time there, and oddly enough, every single one of them seems to have come up positive at Blink (which raises a red flag for me because I'm EVE paranoid). Once again, the apparent attitude that it was only worthwhile for Somer to the extent that it could be monetized is rather contemptible, as though having a successful in-game business that really made a lot of players happy (and earned Somer more ISK than probably anyone in EVE) just wasn't good enough.
On the bright side, that huge void will eventually be filled by someone (or several someones). Anyone with the talent and resources to do something similar will be scrambling to be the next Blink precisely because Somer had more ISK than God. History shows that EVE players will line up to gamble their hard-earned ISK for a shot at quick, easy winnings, even if the cost of service is quite high.
