Amazon is its own shopping search engine. It won't suffer much even if Google blocks it. Apple has its own ecosystem and cult. It's safe for the time being. Google owns advertising, the major mobile OS and search. Anyway all of them could be offered separately in a better way. Advertising and search are easier to overturn than Android. Facebook is hated but is owns messaging outside Apple's boundary. Network effects protect them but network effects could destroy it as quickly as they built FB's lead. Netflix can be overturned by any competitor with a cheaper plan. These are my votes in reverse order.
