Mirrors are just mirrors, they are not build farms that build from source. I would convert the next sentence in math logic and prove you that it makes no sense but not sure you can understand the symbols so let me try again in English. 1 Mint does not trust Canonical 2 Mint plugs their users systems directly to Canonical untrustworthy repos to run possible "evil" binaries and scripts as root. if 1 and 2 are true then as a user you should not use Mint, as a Mint developer you should start working and finally create an independent distribution. IMO 1 is false, probably they mentioning "trust" was a mistake.
