They do not: Mint, while based on Ubuntu, is independent and takes its own decisions. For example, the current source of all the hatred against Canonical, their forced implementation of snaps, isn’t present on Mint.

Well, that depends which one you mean ;-) They’ve been extremely good about staying away from snaps, which is fantastic, and they never did the 'advertising banners in apt update nonsense. They changed to systemd as well, which was a controversy at the time, but most distros have done that now.
