Some folks try to deny that, but those of us who were there knew it. In fact, 'qanon' was the very phrase / term many q patriots used to connect with each other in spaces outside of the chans and the core forums of reddit (pre-au8gust 2018), voat, etc.

This post came in October of 2020. That's virtually 3 years in to the operation, and also a few months prior to the end of the regular posting by Q (Dec 2020). I think Q realized that they need to clarify this point, as the Deep State propaganda machine (aka mainstream media) had hijacked the expression, and used it to mean something completely different from what anons had been using it as.

The distinction between the Q drops themselves and the varied, diverse and sometimes infiltrated theories and interpretations etc, put out by anons became important. What better way to emphasize that distinction than the content in this qdrop?

We could make a list of things that are not of Q, but which became, for certain periods of time, wrongly associated with Q due to the efforts of mainstream media.

The recent articles by various sources about the "Qanon cult leader" are a good example.
