Is that likely? People who don't trust things backed by the US gov't are unlikely to be fond of SELinux, but even beyond that, AppArmor is used in preference to SELinux by the Debian and SUSE families, which probably gives it a greater share of the Desktop Linux market (vs SELinux, mostly used by the Red Hat family) even without ideological/trust issues in play.
I'm skeptical that there's much overlap between "people who seriously use TOR" and "people who use ChromeOS", but yeah Android is a fair point. (And I'll certainly grant that there are probably more Android devices out there than laptops/desktops running Debian derivatives.)
