Apple was a pioneer of an accounting technique known as the “Double Irish With a Dutch Sandwich,” which reduces taxes by routing profits through Irish subsidiaries and the Netherlands and then to the Caribbean. Today, that tactic is used by hundreds of other corporations — some of which directly imitated Apple’s methods, say accountants at those companies.
Apple literally invented the technique. Others followed to compete.
Personally, I support any and all means of tax avoidance, so I don't count it against them. But I love bursting Apple Fanboys bubbles.
Oddly enough, that usually involves saying Apple didn't invent something.
