it took me many decades to decode the economics of the intense Desktop Publishing era.. as far as I can see, Apple made hardware, requiring long lead times, large cash reserves, deep industrial secrets.. while Adobe made software and intellectual property, which was fundamental to the written word, changed the entire publishing world, but was copied without paying Adobe. The ecosystem of developers, business and small business around the publishing world, was watched by every literate eyeball, but did not have a transaction model that made Adobe money. Apple in comparison, made plenty of money on each new sale of hardware, but the infrastructure to do that was huge and expensive.
When Apple turned on Adobe, over and over again, I did not understand how "Apple bites the hand the feeds it" .. Adobe was a likable brand. Of course, Microsoft betrayed and undermined Apple not repeatedly, but as often as possible, inventing new ways to do it with vigor. No review is possible without mentioning the day that Apple, Microsoft and Adobe were on stage at a trade show, and Apple+Microsoft announced the TrueType standard, and John Warnock literally wept in front of thousands with the shock and betrayal of it.
very strange days indeed
RIP John Warnock, bright intellect, inventor, leader
