To transition into something resembling a government would not be very on brand for Apple. If anything they seem likely to blast off into space and colonize Mars with all the cash they've mined and stockpiled here.

And serve as the local authority there for at least awhile.

It might follow something like this pattern, sans prior residents: https://en.m.wikipedia.org/wiki/East_India_Company

A place inhospitable to life? Yeah, this sounds a great plan to waste all their resources...

Well hang on, making human life multi-planetary is extremely valuable, if not essential for our future survival. And we can use technology to make Mars hospitable.

Yes, but Apple is very unlikely to achieve that, as not only it doesn't only take money, but all the money on the earth wouldn't be able to achieve that with current tech (or even next-decades tech...) We should instead concentrate on mitigating the ongoing collapse of our civilization, so that the next one might get a shot at that ! (And Apple is not likely to help here, on the opposite, they are too invested in kicking the can, which makes things worse.)

How would that benefit their bottom line?

By having a planet where only Apple products are available and the inhabitants are a part of their cargo cult, maybe? hah

Taxation, typically.

Mars colonization would fit well, just like their recent products shiny and beautiful and utterly useless

Given the amount of money, employees and resources these companies have, you can see that they are becoming and behaving like independent pseudo-nation states.

Each of these companies (FAAMNG) apparently are more worth or near worth the GDP of Luxembourg and other developed countries and their businesses are built like an entire economy.

There are also do’s and don’ts with some of them i.e rules that one citizen should follow. Don’t touch/hack google3 or you will be arrested. Thinking about virtualising macOS/iOS? You will be swiftly dealt with the Supreme Court of Apple Inc, You disagree with Mr. Zuckerberg on his platform? You will be expeditiously banned and charged with high treason with your real name, address, phone no. set to public for the whole world to shame you and list goes on.

Facebook has a population of 3B people and still calls it a community. If it were a country, that’s like the population of China and India put together. They have a town square, news, emergency services and more. The problem is it’s founding member Emperor Zuckerberg still doesn’t understand privacy and trust with its users despite the scandals of the 2010s. If it were a nation state, then it would be like an authoritarian one.

Ladies and Gentlemen, welcome to the People’s Republic of Silicon Valley.

I understand the GAFAM, but is Netflix even in the same ballpark? (It's also extremely dependent on Hollywood, isn't it?) And Microsoft isn't in the Silicon Valley...

It's a play on faang. Which excludes Microsoft because cool people like Paul graham think (wrongly of course, as usual) I that Microsoft is dead

Which excludes Microsoft because it was a stock-market term for hot tech stocks, at a time were Microsoft already was "established and boring".

Paul Graham ? Isn't "FAANG" specifically about Silicon Valley's labor market and local politics, but hardly relevant outside California ?
