If you absorb the sentiment of most posts, I think rather it was due to confusion over why loyal forum members (who may, or may not support OC's financially) are seemingly treated differently (better?) than loyal customers (who obviously do help drive OC's financial success).
Loyal forum members are understandably defending the stance... after all, this 'secret offer' was posted in the community forum to a thread that only the most supportive of forum contributors can see it (winner winner chicken diner, as it may save some from the mercy of scalpers). Loyal customers on the other hand (who don't necessarily contribute to the forum's sense of community, but certainly support the business financially) are understandably wondering why this approach makes sound 'business sense'. Ultimately, it's OC's business, so OC's call... if people don't like it, I guess they can vote with their wallets.
I think the real question that I'm sure we'd all agree on, is just why are we here again?... Why do OC's (and most other retailers in fairness to OC) seemingly fail to try and do more to get these 'toys' in the hands of people who are genuinely passionate about owning them? This 'secret post' is a great example of what can be done with a little thought and consideration (kudos to them), but unfortunately it will only benefit a subset of people (who may, or may not have sound OC purchasing history).
...anyway, deffo don't be grumpy... life's too short to not let people express an opinion
