Following Gartner [1], 60% of all devices shipped in 2014 have an OS based on Linux or delivered by Apple.
Do you think that a law that prohibits making other people slaves is non-free in nature? Because the GPL prohibits something similiar.
i don't just pull my opinion out of my arse, at least not entirely... :)
your source of figures is very dodgy. you need to account for the devices that aren't brand new, and especially third world and the millions and millions of cheap androids and desktop pcs. looking at america or limiting to new purchases is very special and has nothing to do with the wider market (its not uncommon for people to have a "who buys these things new? what a bunch of idiots" mentality in poorer parts of the world). Apple do much better in the US than anywhere else, and new purchases are not the majority of devices in use in the wild.
try a google search like this:

and pick from many many sources of more useful figures
as you can see from very many sources, aside from OS X - which is not really a linux, gnu/linux may as well not exist.
Just remember, hyperbole serves no master. Employ it at the risk of having it employed right back against you.
Most people would say that it's ridiculous to compare drivers licenses to slavery, even libertarians will tell you it's a loss of freedom but few would compare it to slavery, because for the most part drivers licenses and slavery have nothing in common.
Freedom is something we are born with, and I am free to do what I want with any software. The GPL asserts rights based on societal understanding to the contrary. Most nice licenses just ask for credit if its appropriate.
This idea that having priority in solving a problem entitles you to something is harmful for the whole of society for the whole of the future.
I wasn't advertising any political goals. I just thought that the idea behind the GPL wasn't understood and wanted to make it clearer.
