Adding your user to the docker group is in the official Docker install instructions, I wouldn't call that "random copy paste guides".

You mean the optional post install instructions, which is a separate page from the main install instructions, and contains a giant warning about the security implications?

If the official sudo project had a guide on how to disable passwords, that shouldn't be taken as endorsement of having that as a default config.

		Per my other comments, it does not really matter if you disable the sudo password or not. If you have a sudo binary at all you effectively are giving every user process root since malware can mask the sudo command and intercept the password so trivially.
