I'm not sure why shareholders are upset, Davie achieved several milestones and was rewarded handsomely with stock in his own company (which he immediately sent out to friends, family and of course the market to spread the love around)
Sure, he reverse split the thing into oblivion, but all in shareholders interest so that one day MULN will be trading at $260,000 per share.
You have to think long term.
Just my take on it and, yes, that is total nonsense......🙃
