That's a strange title and misguiding one, if the Bitcoin community is a Sybil Attack on Bitcoin then why Bitcoin exist in first place? Bitcoin is Bitcoin because of the community and support it's getting from the community. Without the community and users Bitcoin can't really be a useful thing at all, so it's better to not use such misleading title.

I know that Sybil attacks are of a concern but considering whole community as sybil attack is not right at all. I know that sybil attack is a concern and it was a concern back then also but it's not fair to consider the whole community as sybil attack on Bitcoin.
