Well I can tell you I get downvoted for mentioning zorin and from comments it would seem it because they have a paid option. The funny thing is I get complaints because the paid option does have a perk (a gui chooser for emulating a osx or choice of several windows versions) and a linux distor should not be doing that but I also get the reverse that the paid perk is a stupid thing that is not worth it and pointless. Granted paying gets support the usual perk. I kinda thought ubuntu had some sort of enterprise thing to get formal support but maybe only suse and redhat did that. So there are definately some folks that get something in their craw if a paid option is present. I will say I hope zorin is passing on at least half of anything it gets to ubuntu who should be passing back to debian who should pass back to kernel development. I mean zorin is really pretty stock ubuntu lts with a bunch of preinstalled software and some gui tweaks so that the computer is pretty good to go right after installation. I guess though most respins are like that. Just prechosen configs and software packaged together.
