If I were an unscrupulous person I'd certainly be tempted to fire up some bots and spam the heck out of every blog I can find with anchor text nofollow links to my competitors' websites.
The way things are going, you might be doing your competitors a favor. Those links can actually bring some traffic in their own right on occasion and who knows when such an action actually results in more traffic than the traffic they will lose from G as a result of your actions. Particularly if they were going to lose it anyway in some futuristic Google shuffle. I'm being a bit tongue in cheek here but sometimes flipping the argument on it's head can be enlightening in its own way. This refers back to the concept of going back to what worked before G decided what the "proper" way of doing things should be. Who said they're providing the best answer to my query anyway? Only I can answer that and I can only answer that if I have access to all the possible answers. As webmasters it's easy to take G's results personally least you forget that another 9 million or so possible answers also exist. What makes my solution any more special than any other? I don't think it's about whether your solution is commercial or not. It's about whether your solution is commercial enough to warrant attention.
I don't see Amazon getting squeezed out (which should emphasize the above point).
slowly squeezing everything with commercial intent out of the organic listings
