yep, expect it. It's why I don't buy sog knives anymore. a 60 aegis shouldn't have bladeplay but mine's terrible. Especially when I can buy several spydercos for less money that have no problems at all.
I think they don't care, honestly. I've heard several people don't have problems with them, so maybe they have spotty quality control. I'd buy something else, kershaw has several flipper models that would work better.
