I ran through a website called Ubuntu Video that seems to affiliate itself to Ubuntu, including by using their visual look for the website. The copyright and the hosting does however make it separately hosted from Ubuntu/Canonical websites. But I'll let you discover in picture what I clearly do not like:

Something about Free Software, Open Source Software, and a placeholder for something that obviously require a non open source friendly technology was a closed source implementation to view. Yes, I can't view these Ubuntu Flash videos on my stock Ubuntu system using Free Software (gnash is far from being stable for me to risk to allow it to crash my browser).

The creator of the website even try to justify it for the "hype". Is that being honest? I wonder...
