Even if you're right, the chances of building a company on debt with an unproven / new technology in an extremely competitive field that has competitors with tons of capital like Dupont is a fantasy.
It's even worse when it's toxic debt / "death spiral" financing that's supposed to be paid back by revenues from fantasy companies in South Africa that have never shown a track record or a balance sheet and can't start paying the fantasy monies because US interest rates are going to start to go up is a double fantasy.
But it looks horrible to have the company's biggest revenue source push back receipt of payment because of some very sketchy excuse of US interest rates.
