^ Further pointless observation to add to this. Still yep ... going to do it anyway. Ubuntu also has to contend with open source code and FOSS etc licenses in the software they use. Thus unlike M$, which can hide who know's what in their closed source, strictly in-house designed operating system and software. Canonical Inc has no choice but to work with MUCH greater transparency, so much less chance of doing sleazy things and not getting busted and discredited if they were to get too far out of line with it.
Imo ( well more like I 100% know), not that there aren't many ways to stash or config stuff in gnu/Linux that would be totally unappreciated were it to come to light. Say something like how the kernel or other junk associated with the distro has been patched, this ... that etc. Could very well be far less likely anyone is truly going to go through the trouble of intimately examining every piece of the distro and auditing it down to it's lowest levels.
Canonical Inc still has many people watching it and a HUGE userbase to account to if they were to do something and/or get caught doing something too inappropriate. The whole Unity ordeal had me rolling around on the floor laughing butt off. Any 1/2 competent nixer could've just removed it, installed and config'ed their DE/WM of choice and gotten on with their lives. Still though it was a boon to LM, as people mass defected fleeing unity to this (imo much better gnu/Linux distro). So I didn't bother being very vocal in pointing out how silly those users were being. Plus stuff like MATE/Cinnamon emerging from it too ? With gnome3 and etc. Rather than shoving a particular DE down it's users throats. So overall win, win ... win and WIN for nixers everywhere !
Last time I checked (distrowatch), Linux Mint's still #1, still #1 .. still #1 !!!!
Gooooooooo MINT !
