"It had been proposed that a check box in Ubuntu's Ubiquity
installer that gives you the choice to install third-party software
should be selected by default. This would have required users
downloading the latest version of Ubuntu to proactively de-select
the box should they not want the non-Ubuntu options installed with
their fave Linux distro.
"The justification for the proposal was YouTube: people would be
deterred from using Ubuntu if they fired up their machine, hit the
Tube, and found it didn't work, according to the thinking.
"The problem is that most video on YouTube is streamed using
Flash, a proprietary media player that uses the royalty-encumbered
H.264 video codec."
