Don't trust corporations, especially those where one egomaniac has all the power.
I disagree with the inference of the second part, publically traded companies are forced by shareholders to lay off workers and sabotage long term plans for short term profits all day every day, and they're emboldened and desperate knowing their grift has nowhere left to grow/metastasize on a finite world they've already largely raped, pillaged, and conquered for it's capital value.
The problem isn't whether one egomaniac majority shareholder capitalist or 1,000 egomaniac shareholder capitalists let their insatiable greed disease do the managing.
The problem is capitalism and the worst of human impulses it stokes exclusively by design.
Fuck Elon Musk the blood emerald heir with a bachelor's degree playing pretend he's Tony Stark though.
