Spiralfrog and "jumping through hoops"

Spiralfrog is a company that offers free downloads of music that are "free" because you have to listen to advertisements. You may not copy the music, so it offers piracy-prevention features to music companies. You also need to visit the site of Spiralfrog once a month; if you don't, the music will be de-activated, and you won't be able to listen to it. The New York Times has an article on this company that's supported by Universal Music Arguably, these are not very draconian measures. Once you get used to doing these, you won't even notice that you're doing them. But how many hoops are you willing to jump through to get to "free" music for the first time.

1. Is this the simplest they could make it?
2. Why restrict copying? If people shared the music with ads inserted in the music, wouldn't that increase the number of ad impressions?
3. With so many web based businesses offering ad supported free content, isn't the customer going to tune out when she or he hears the ad? What about Ad Fatigue?
