It has to do with morals and ethics and if what you say is true and that person is representing himself as either you or author of Tiny Core, then:
a) ask them nicely if they will specify - "we didn't author the base package - we just added "THIS" (assuming they enhanced "this")
b) if they post that then they did TC a favor getting the package into the community.
c) if they suggest they wrote it, they deserve a truckload of legal bricks dropped on them and
b) the person who paid them or encouraged them is the real threat - unless you are aware of why this particular person would make such a blunder, and
c) are you sure that person is a real person and not a front for someone else?
