Those who do not learn
In the late 80s Apple was riding a wave, successful despite numerous incursions into its markets. However, it then got bogged down in a series of lawsuits. Simultaneously, ttheir platform was neglected by many (developers, users etc.) because of the locked-down nature of its products.
Of course only a complete idot could make exactly the same mistakes again and give away their hard-earned return to success?
