He makes a good point. Since Google recently went after the content farms that hurt their search results, it would be nice if they extended that to authors and legitimate content producers.
It doesn't make sense that when you search +"title" +ebook you get almost only pirate sites. This is the same problem that used to exist with music. Unless it becomes easier to buy ebooks legally, the "pirates" will win.
This is not really Google's fault only though... Some weeks ago I tried to buy a scifi ebook, but was bounced by Amazon because I'm not from the USA. In other stores I had similar problems.
Authors: at least make sure everyone can buy your ebook legally!
Maybe another search engine?
