I understand the sentiment and might have had difficulty approving the sale if I were on the Hertz board of directors, however, there is a chance, however slim, that the dumb money knows something the smart money doesn't.
This is much more-readily seen post-GameStop. The AMC theater chain, mid-hoopla, managed to discharge much of its debt. The gamblers at home literally saved a major US business from dire financial straits. Some of them got paid for it, too. The company is in an undeniably better position today, as are any of the retail investors who bought and held. (The share price is up 10% today, too. The world is a complicated place.)
On the scale of exploitative acts, enabling informed gamblers to play chicken with the Bankruptcy Bus, while it may be exploitative at some level, may not be as egregious as other exploitation (Casinos? State lotteries?) that we tolerate every day.
