The Free Software Foundation has launched a campaign to convince computer users to give up on Microsoft's Windows 7 operating system.
"Our growing dependence on computers and software requires our society to re-evaluate its obsession with proprietary software that spies on citizens' activities and limits their freedom to be in control of their computing," said Peter Brown, the director of FSF, which was created nearly 25 years ago.
The Windows7sins.org website lists 7 Sins of Microsoft's latest operating systems. They include Poisoning education, invading privacy, monopoly behaviour, lock-in, abusing standards, Enforcing Digital Restrictions Management (DRM) and lastly Threatening user security.
They argue that doing so would increase their reliance on Microsoft; instead the FSF reckons that they should instead try using GNU/Linux and open source solutions.
The group sent 499 letters to the top Fortune 500 organisations in the US - leaving Microsoft out - urging them to reconsider any upgrade plans to Windows 7.
For each 50p donated to them, they will send one additional letter to IT decision makers (which we reckon are all based in the US or else the 50p wouldn't be enough to buy the stamps).
The FSF convened those interested to join them at noon (US Time) in Boston, Massachusetts and apart from targeting Amazon in the past for its stance on e-book DRM, the foundation is also set to take on another popular operating system, Apple's forthcoming Snow Leopard.
Matt Asay of Cnet pointed to a sweet irony. The Windows7sins website bears a copyright mark and uses a license that prohibits derivative works, Creative Commons Attribution-No Derivative Works 3.0 License.
