Well the thing is, whether you like it or not, people want access to special things nowadays. It's a good marketing tool, and trust me, if there is any realm Tripwire needs help it's in the marketing department.
They are incredible devs, but just don't have the marketing to get their goods shown to a large enough audience.
If you ask me, Tripwire could and should make HoS a household name, you know damn well the real fans will get the bugs reported regardless. Whats a little extra cannon fodder gonna hurt?
