Google's "Don't be Evil" model should definitely be questioned sometimes.
Google's practice of delivering free software in the interest of selling more ads is arguably evil. So is the practice of selling ads in association with other people's content.
Do consumers really benefit by Google apps gobbling up office application market share from Microsoft and others? The software is free but is it really free? It seems to me that we're trading quality productivity tools in order to be bombarded by distracting ads.
Now Google is rolling out google TV. Some have said it is the beginning of the end of TV as we know it. By compiling all of the free sources for content on the web, google is undermining the ability of the major networks to generate ad revenue.
So now Google is planning on selling ads in association with video content that other companies paid to have produced while simultaneously undercutting those same producers.
