Not that farfetched really. I don't understand how/why buying a social media site contributes to that "mission". But Elons a narcissist so it could have very well been an ego buy. It would be good to see a billionaire step up and have the financial weight to actually make a difference. But when the system is built to benefit the rich. Honestly I see even those with the best initial intentions being caught up by greed in the end.
