If that's true, why did we see three significant Bitcoin services get hacked in basically the same way in the last year? I'm talking about the Linode ones.

Events like this encourage better thieves.

Because the people running these services apparently cared more for quick money than for security. Or running their own server. I mean, who runs that kind of thing on a cheap rented server? No pity here.

They took a risk, and one don't always win when taking a risk. (You startup folks should know.)
