1) making someone aware but saying right away that it's fine (that's what IBM as a self-declared friend and protector of open source should have done in this context)
2) making someone aware and offering a license deal on fair, reasonable and non-discriminatory (FRAND) terms; that would have made sense in this case, too, since TurboHercules stated in its first letter that it wanted to reach an agreement with IBM on such terms
3) making someone aware while simultaneously pursuing exclusionary, anticompetitive objectives
I like the first possibility, I can accept the second one if the offered terms are truly FRAND, but I despise the third option.
