taking the money and running is the dream of the VCs
if you believe the milton friedman approach to economics, a company has no other value in that what it can provide to the owner (shareholder)
take your millions while it burns and, as the parent said, never fly commercial again
For a VC "running" would mean re-invest in the next thing to get more money. What alternative would you prefer? Keep doing the same thing without investing in new stuff?
They don't "take the money", there are other people that believe some things (profits/growth in a field) will last forever and will bring 10x return, so they are willing to give them the money.
