Access to the proprietary world

Who doesn’t like the idea of open source, of sharing, and that every one who is able to can change software to his/her likings and share the changes with the rest of the free software world? Unfortunately, it takes a big deal of self-restraint to only use completely liberated software.

Who can resist the attraction of shiny animations on websites (Flash), or those of playing music on your iPod (which does not support any of the free formats that are superior in so many ways)?
