So... I'm kinda new to Q, so had to do some research myself as I didn't know who John Perry Barlow was/is...
I found this great article written in June of 2020 that explains a lot & more about this post & more, including additional Q posts.
There are alot of links which are also helpful.
Many people involved, it goes so deep, wow. I've learned a lot.
