Sure, and if they need more money they can go to VCs. However Im suprised VCs will give them all the cash up front. Figured it'd be something like, "Hey I'll commit 1Billion in cash to your needs, however I'm currently holding it in a mutal fund myself. Let me know when you need it"
There are certainly battles they are fighting but if they have over $5B in cash reserves and are profitable to an extent that's no where near the fight that Uber was waging in China were it was burning (net loss) of over $1B a quarter.
