When you join a company, especially a start-up, that is clearly and publicly losing a massive amount of money, there is some onus on you to be aware of the risk.

I assume parent meant that if you work at a company, it is your responsibility to know whether the company will last for the time you intend to be there. Without knowing the risks involved, if the company goes under and it is clear that it's a scam, you losing your job is partially your responsibility.
