They don't need to apologize.

I never cried "scam" and I always maintained that Avalon, at least, actually did ship. Even so, I side with the sceptical here. They did nothing wrong. They pointed out, however shallow the logic, that there was a chance that Avalon was a scam. This is more information to everyone. This helps avoid groupthink.

The doubters need not apologize. In fact, I would like to thank them. It helps prove to the real scammers how difficult it would be to scam the community, such that even legitimate products are labelled scams. It ensures a better, safer community in Bitcoin's future.
