Similarly, Google presents its derivative work as Android, and it exercises its rights vigorously to defend the perception of its marque.

Obviously, I'm just pointing out the fact that there are different groups of users for both products and one group isn't likely to be influenced by how others use the trademarked goods. Android has common people for its clientele, Grsecurity has security professionals that will judge it based on its intrinsic merit and not on what some subsidiary of Intel once did with it. Grsecurity de facto doesn't need to be defended, even if de jure they are entitled to the protection. That's why this is nothing but a money grab, what bothers me though is that they try to package it into something that it is not.
