It's happened a couple of time where people have publicly named and shamed some company or person on either a mailing list or diary entires or their own personal blogs. I don't think this is the right way to handle things, and while these claims need to be dealt with I think we should first try and contact people about properly attributing OSM, otherwise it may only end up backing people into a corner and we may loose a valuable opportunity.
Here's a slashdot post from last year that details what happens within the GPL community: http://news.slashdot.org/story/09/11/10/1540242/SFLC-Finds-One-New-GPL-Violation-Per-Day _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
