I'm just in the market for a camera from this family and was tossing up between the Contour and the GoPro (with a slight leaning towards the GoPro).
The Sony was out due to their ongoing complicity with the RIAA et al (I won't buy anything even with Sony chips in it unless there is absolutely nothing else on the market that meets my needs).
Thankfully, my decision has now been made for me - thanks GoPro!
Ethical purchasing is the only way we'll fix these thing. The age old problem with capitalism - profit has nothing to do with morality.
