Some fairly intelligent folks have had, or continue to have this viewpoint. As an example, I was extremely delighted to meet Chris Dixon, whom I still consider to be rather intelligent and diligent fellow. When we met, in 2013, he was all about Bitcoin and the blockchain so I tried to engage him in conversation about it. The first thing I asked was what he thought about the fact that it was being used for some fairly nefarious things, but was not, in fact, anonymous. He was convinced it was anonymous. I attempted to bring up some points to convince him otherwise but found it to be a rather short conversation. So, you may be as surprised as I was that it's relatively uncommon knowledge, even for intelligent and diligent technical folks, that Bitcoin != anonymous.
