There's a variety of options that are available here, and I don't buy the argument that AMD's behavior is automatically unethical.
A. Company makes and sells hardware, and offers no software.
B. Company makes and sells uniquely featured hardware, and offers software that uses those unique features.
C. Company makes and sells hardware that adheres to an industry standard, and offers software that targets hardware adhering to that standard.
D. Company makes and sells hardware that adheres to an industry standard, then uses their position in related markets to give themselves an unfair advantage in the hardware market.
Of these, options A, B, and C are all acceptable options. AMD has traditionally chosen option A, which is a perfectly reasonable option. There's no reason that a company is obligated to participate in a complementary market. Option D is the only clearly unethical option.
Intel's legitimate course is to make their CPUs run actually faster than the competition, instead of tricking people into running slower code on the competition.
