There is some potential for you being right.

There is also a lot of potential for you being dead wrong.

Baen Books has already tested this theory. They have authors that give away 1 or more e-books WITHOUT drm. End result. their paper sales INCREASE. In many cases the sales of ALL their paper books increase, not just the one they gave away as an e-book. 

There is a reason people have given away free samples for 1000's of years, it increases future sales. The main difference in this case is the free samples you are screaming about are NOT paid for by you or your publisher. Be happy if you are getting free advertising. Its like that advertising all smart authors pray for, word-of-mouth advertising. Its free and its the most effective.
