It absolutely applies at cash-rich companies as well. Losing money is losing money, no matter how much you have in the bank. I don't know why folks seem to keep thinking that having money means you can lose it forever, or that out of the kindness of the company's heart they can continue taking investor money it and funneling it back out to non-productive activities. For-profit companies exist to make money. Investors were willing to put that on hold for 5 years because interest rates were low enough to make borrowing cash effectively free, allowing you to trade cash in the short term for growth. That is no longer true, and they're no longer willing to do that.
Put more clearly: investors __do not want to invest__ in companies that are burning money right now, no matter their cash balance. Responsible, profitable growth is the goal. Your cash backstop is not relevant.
