The number of photos is irrelevant to the analogy, though, as is what people do with the photos afterwards. If the bikes are visible from the public street, people can take as many pictures of every bike they want, and then make money from them if they want. It doesn't affect the owners' usage of the bike (unlike the original analogy, where the owner loses access, which was what I was trying to correct)
Physical analogies for this kind of thing are always flawed, it's just dishonest/misleading to pretend that copying data is ever analogous to taking a physical object (the owner of the original is never deprived of the original when data is copied).
"I don't know the business model of linkedin"
Most of it is selling premium features to recruiters and other businesses. I'm not sure if Hi-Q's service interferes with that or not, but LinkedIn should not be trying to have their cake and eat it by leaving things in public then complaining when the public accesses it in a way they don't like.
