Say you're a US citizen. You can choose not to buy an Apple product. You cannot chose to not pay your taxes.
This is just one of many distinctions between a government and a corporation.
But you can move to another state/country. They aren't claiming it is apples to apples but claiming apples to oranges is disingenuous at best.
Apple does not have tax authority over you.
Apple does not have a monopoly on the legitimate use of force in any geographic region.
Apple does not pass or enforce laws or have citizens.
It is big and rich and powerful, and like all big and rich things with that much reach, literally cannot do anything without making someone angry.
This does not make it a government, and pretending it is one is a silly distraction from holding it to account when it does something bad.
I can't understand why you'd think that.
What characteristics of a government do you think it has? Assets and income? A government is something that 'governs', not something that has assets and income.
It is a de facto government with assets and income that dwarf most U.S. states, as well as most foreign countries and many multinational companies.
Calling their legal compliance obedient is a cruel disservice to the facts of their constant political maneuvering.
