Text: This restraint may partly reflect Microsoft's market strategy--after all, Microsoft beat Apple partly because Apple did practice vertical foreclosure, and as a result inhibited the development of complementary software (although the main problem was Apple's persistent belief, despite all the evidence to the contrary, that everyone would be willing to pay a premium price for a niftier machine).
Entailment: Apple believed people would pay more money for fancier machine, even though evidence said otherwise.
Contradiction: Microsoft has a strategy to beat Apple but it hasn't done it yet.
