Can you please give a link to the announce from Red Hat or someone else urging their users that they don't need to upgrade? It would be the last thing closing the question.

You as a Docker developer see the post as an attack on your project. But most of sysadmins and kernel developers see it as a nice example of the fruits of invisible long work - when well cared system with accurately configured security restrictions saves from some vulnerabilities.
Anyway, it not means underestimation of the Docker and you great job. Sorry you've got stressed by all this noise.
