"Diversity" is more than the absence of racism. Diversity does not mean grudgingly tolerating the equality of those different from you, it means recognizing the real, additive value that disparate perspectives and habits bring to your life, and others' lives. It doesn't mean tolerating differences, it means valuing differences. Tolerance is just the first step on the road to diversity.
Freedom of speech does not mean waiting for the other guy to say something before you shout him down. Free speech means, as the saying goes, disagreeing with what someone says but defending to the death his right to say it. You only really value freedom of speech when you quietly thank your higher power of choice that the other guy has the right to make your blood boil.
So it is with open platforms.
Openness is more than the absence of closed. Openness does not come automatically just because you deploy an industry standard. Openness means you recognize the real, additive value that disparate products and businesses bring to your platform. It doesn't mean tolerating competition, it means valuing competition. You only really value openness when you quietly thank your higher power of choice that your competitor just took advantage of the opportunity to destroy your business on your own platform. Implementing standards is just the first step on the road to openness.
Steve Jobs, you fail at openness.
