I've installed Chrome Version 74.0.3729.131 (Official Build) (64-bit) on Fedora 30 from the official google-chrome repository, and if I go to the chrome://settings/help I see the little "Your browser is managed by your organization" thing on my home computer (so no organization).
So, I go to chrome://policy and see two entries for the policies:
AuthNegotiateDelegateWhitelist *.fedoraproject.org
AuthServerWhitelist*.fedoraproject.org
How can I disable this "Your browser is managed by your organization" stuff and remove these whitelists?
