The fact that a reservation queue is needed in the first place?
It's a perception issue. People tend to overhype anything that Valve does as a whole.
Nobody would be bothered much if this was some small Chinese Kickstarter project doing it but Valve is acting like this when they're a multi billion $ company with decades of experience.
Besides, do measures ever work? Every year, scalpers still somehow manage to bypass the system and resell en masse.
Valve's new reservation system is designed to make the Steam Machine launch more orderly and fair. The approach has gone down well with the community – but the account requirements completely exclude one group of potential buyers.
