I was just surfing

I know I know, many people will just disregard this thread with the words, 'Oh just another scam I've heard many time before.' But that's not what I'm trying to get across.
To justify my point, look at this video from youtube from a popular news channel in america that has reported the market:

Also, from this website, the author of this post received many free goods and also explains HOW it is possible for the companies who give the products away make a profit:

I know that I-hacked is a trusted webstie and many people use it to get the best from electronics - so the article in the link IS legitimate and wouldn't be written from someone who is just working from these companies.
Maybe one of you has done one of these deals before? How did it work out? Do you suggest that I try it? All comments are freely welcome.
