Disclaimer: The headline of this thread is my own speculation.
Look at Huawei’s foldable Mate X phone. It’s years ahead of anything Apple has. And the price of foldables will go down just like all new technologies. And what kind of hardware manufacturing does Apple have? I don’t know but I know that they outsource the manufacturing of iPhones for example, which means Apple is dependent on other corporations who sooner or later can take advantage of that and screw Apple.
Apple’s software is equally doomed in the long run. A few years from now both Google and Microsoft will run progressive web app OSs with a lot of apps using WebAssembly and Apple’s siloed software model with become obsolete say within a decade.
Facebook is another beauty. Facebook’s one trick pony business model is vulnerable to be replaced by a new big social network. Facebook is not likely threatened by small companies, but look at for example Google+; does anyone really believe that’s the best Google can do?
