Surely almost everybody paying to get "designer access" already believes one of two things:
- They have no useful skills to offer except a few ideas, so it's not like they're being insulted. This is just a cool opportunity for them, like a paid internship.
- They have some awesome ideas that the industry has ignored, because the old designers have no idea what they're doing.
Either way, I don't see much conflict between what Garriott said and the motivation of the people taking up that particular pledge level.
And on the whole, that specific pledge level is just one among many. It's more important for him to drive traffic, even if a few people drop off that particular pledge level. Given that uptake for both the level before it and the level above it are higher, it suggests people are generally not all that bothered about this specific offering (and sensibly so).
