*this is in no way a defence of Musk it's a pointing out how ridiculous it is to see a problem with him but not care about the other obscenely wealthy capitalists who not only exploit labour and hoard resources, but also basically own government via either corruption (aka "lobbying") or direct representation (ie all the rich fucks in government making rules for themsleves and their friends), just like Musk, simply because they're "polite" enough to do it behind closed doors.
That's not to say don't buy the things you need, it's to say don't be deluded in to thinking that it matters. As long as capitalism exists, governance by and for the rich isn't going anywhere, and your money will always be going to one of maybe a couple dozen people.
