Acronyms like FAANG are nice, but these companies have little in common apart from their success.
How would you break up Netflix? It's pretty much a single business of distribution. Ok, it also produces shows, but then please break up Disney before Netflix comes up for the chop. Disney, which just merged with Fox. Ahem.
Apple? You could try to break up the hardware and software parts, but they're pretty much joined at the hip. The software part pretty much only exists because of, and for, the hardware part.
Facebook would be slightly easier, if only keeping WhatsApp and Instagram separate. But after that, breaking up Facebook itself would be hard; it is after all a single website, almost a single web page.
Google would be interesting to break up. It's difficult to know how much the services depend on each other; like Maps knows which hotel you booked a room for, and knows about traffic jams from Android data, etc. Or the assistant probably knows everything about you from all the different services. Oh, and Ads, which is everywhere, and gets data from everywhere. Just knowing which parts of the business are viable on their own would be interesting to know.
In comparison, Amazon would be downright easy. Supposedly, each internal service already treats the other ones like external consumers. In fact, that is sometimes considered one of the big reasons of its current success in the cloud business...
