Why? Whether something has contributed meaningfully to my research is my decision, not Ole's. Not having light "hinders my science", so I'll be sure to cite Edison on all my papers.
I agree with the sibling commentator that Ole's behavior is jerkish. Not because he asked for citations, but that he misleads users by claiming his request is standard, when it is decidedly not. He also obfuscates the voluntary nature of his request as much as possible, to make it seem like citing is a legal requirement. And he is inflammatory in responding to people who make the perfectly valid decision to not cite him, or to patch the notice out.
