Dear Mr. Gopalan
To your appeal - "Can anything be done about it or is is somthing, we need to turn a blind eye to?", I have to say that plagiarism should not be tolerated at all. Its one thing to use someone's material without permission; but entirely another when one credits oneself with the material.
In this forum, if you see my posts, I have always fought against plagiarism. People using other's material without permission, should at least quote and give credit to the source.
I can understand how bad it feels, when one finds that his created materials are being merrily used by others, for profit, and being passed off as one's own material.
Plagiarism is a shameful act, having same gravity as theft of tangible physical material, and should be condemned by all.
I think we Indians are more susceptible to this evil. Given half a chance we would violate all copyrights and put our names on everything; be it movies, music, books and literature, scientific articles, research papers, project reports; and even training materials and PPTs.
Regards.
