You lack any realistic perspective of 21st century mega-corporations. Guess what? Apple has more money than half of the small nations on Earth.
Samsung, Microsoft, Amazon, Google. They are all wealthier than so many small sovereign nations. These mega-corporations are literally nations unto themselves. A mega-corporation like Apple probably has far more diplomatic power to influence major nations (like Japan, USA, Germany, China) than dozens of small sovereign nations like Tonga, Fiji, and Monaco. So I can understand that these mega-corporations have vested interest when it comes to national politics. Apple (and others like Amazon, Google, Microsoft) have a reasonable need to voice their concerns regarding national policies. National policies affects them. It affects their finances, their economies, it affects their hundreds of thousands of employees, etc.
And just like in the science fiction novels of Heinlein, Niven and Pournelle…. there is no doubt that in the near future, mega-corporations (be it Samsung, Amazon, or Apple) will be in the position to field their own private armies and large security forces, to defend their own interests. Mega-corporations will become political nation-states on their own (in practice if not in name). It's trending in that direction. You just don't realize it yet.
