A Call To Arms
In the eve (very nearly the eve) of the launch of Windows 8, Canonical releases the latest Ubuntu version. In its homepage is splashed "AVOID THE PAIN OF WINDOWS 8'. It is akin to a war cry like the ones bellowed out when two armies faced each other in the field before contact.
Larry the Free Software Guy issues a call to donate the price of Windows 8 to the Linux distro of your choice. (or to any free software project) This is in his Larry the Free Software blog titled "No Thanks. I Got Linux"
