You will find that Steve Jobs did not support many causes at all. . . his political donations are small compared to the political donations of others with his kind of money. When he returned to Apple he cut off all political donations and, although registered as a Democrat, when asked why he did not allow Apple to support Democrat causes, he replied something to the equivalent of "Half of Apple's customers are from the other side of the political spectrum, and I won't piss off half of Apple's customer base by making political or charitable donations they won't like and vice verse." Even his personal political giving during the last ten years of his life was casper milquetoast. . . donating less than $200,000 total.
Any donations attributed to the name Apple actually came from the Apple Employees Political Action Committee. . . which were generally to Liberal leaning causes and candidates by about an 80/20 split.
Apple did not even have a major lobbying presence in Washington.
Apple has become more political since Steve Jobs' passing under Tim Cook, but mostly for civil rights issues and LGBT issues. Even there Microsoft, Google, Facebook and others were doing it far longer and gave more financial support than Apple ever did.
Thank you. It drives me nuts when people throw around the term “leftist” with no backup or justification.
