The article is about shareholder value, not profitability. Anyway, that aside, the article was specifically written to address the people writing Elon Musk's off as "...a self-absorbed corporate carnival barker..." which is a conversation happening within the context of the Twitter takeover attempt; hence, "managerial excellence". Musk's choice to share the article clearly demonstrates that he believes his ability to drive shareholder value to be a defence of his "managerial" credentials. Whether his intentions for taking over Twitter are altruistic or not, I don't know, personally I don't think it's profit driven (but definitely wouldn't describe it as altruistic...) but defending your managerial ability on the basis that you're a producer of shareholder value in a conversation about the ability to run a "global free speech platform" is nonsensical and undermines any proclamation he makes about his intentions.
