The question is who is the author of this post.
It is unattributed, and while clearly based on the CVPR it is different enough that if it were a traditional publication it would be counted separately. If someone wanted to cite this post, what would they cite?
By comparison, distil.pub is a properly citable journal: https://distill.pub/2017/momentum/#citation
I'm confused - for me the answer is quite obvious. The authors listed on the CVPR paper wrote the published paper or are you suggesting otherwise?
