I take it English isn't your first language? I'm sorry but judging from how you write, it strikes me as a lot of word salad so I'll try my best to address your points as how I interpret them.
For the first point, well he's the CEO so whenever their company brings an idea to fruition, normally its whoever calls the shots that gets credited. I mean, if a country is being ran well or poorly, who do you usually attribute its performance to? The president, prime minister, lord, king, or whoever....right?
As to the second point....there's a fine line between proper moderation versus reprimanding or canceling someone's opinions bc you don't agree with them which is largely unfair and violates free speech, and Twitter was largely guilty of that before Musk took over. It was already a cesspool of trolls and bots to begin before he cleaned house.
For the last point, well investing is risky. If someone puts up money, there's no guaranteed ROI. If they lose money, then that's on them. Nothings going to happen to Musk and even if he gets sued, its gonna get thrown out, dismissed, or settled out bc its irrelevant.
