Eh, going to war with a company that:
1) Has hundreds of billions of dollars to spend on war and
2) Controls your distribution and ability to shape/design/monetize your product ~50% of your value-weighted userbase
...is not an ideal situation.
This competition is probably inevitable, so as long as it’s happening it’s wise to try to extract as much antitrust value as possible from it. But it’s hardly a fantastic development. Especially since I think a lot of shareholders of $FB are also overindexed on $AAPL. If you own both of these companies, obviously you’d vastly prefer some kissy kissy makeup over Facebook dumping billions into a Watch, Apple dumping billions into an Oculus, and both dumping hundreds of millions into lobbyists trying to inspire congresspeople to strangle the other to death.
