Several years ago, I bought a KHS bicycle. I blogged about it, and I included the promotional picture in the blog.
Today I had reason to browse around in my old posts and I saw that the picture I used has been replaced with one that reads, "This is a stolen image from KHSbicycles.com."
So I created a free ad for KHS and they were so worried about copyright that they undermined it. Because, evidently, the revenue stream from a copyright-protected picture is greater than that expected from a favorable user review.
