I wasnt tipping ZNO, just stating how even with picking up Jetstar, Qantas and large US institutions for their product its not easy to sell. I bought in at 24c - sold at $1.70 average, kept a few for the long term ride in case they were really successful and expanded (which hasnt happened because businesses dont want to spend any more money on Covid related costs than necessary) - the same can be applied to your original post - the company might come up with a brilliant solution but demand is likely to be weak
