Yeah, not hard to mess stuff like this up.
But there's obvious points to make;
- No DRM & software-lockdown & other
- No viruses/spyware/adware, because of the system's organisation
- Freedom to support whoever (GNOME/KDE/XFCE/Flux, Ubuntu/SUSE/Gentoo, etc.)
- Hardware is almost always going to work, you just need to find the right distro
- Runs on old and new hardware
- Lots of apps that replace MS/Adobe stuff
- Feeling 1337
But it can't be directly anti-MS. Ever. Offensive campaigns never work, or if they do work, they don't always give the intended results.
