In my view it's just the rising interest rates are drawing capital out of the speculative end of the market (I'm generalising, without looking into the company specifics)
Investors aren't interested in 'what if' scenarios and high risk speculation for future growth, particularly when the risk free return is somewhere around 4.6-5% atm in alternatives like cash.

A quick flick of the quarterly in Oct- Dec 2022 looks like it's a loss maker and still in 'growth mode' (my words). Big operational and admin costs that aren't covered by receipts.

Perhaps the disgruntled investors you've sensed are amateurs that have been drawn in by a story/expectations/ramping. There might be a lesson there
