Very good points, and Elon Musk is sure he can pull it off anyway. Having a population completely reliant on your company store for every single thing they need to survive is an enormously attractive proposition to megalomaniacs like Musk, and he has dreamed of this power all his adult life, from what I've read. The recent revelation that Musk personally disrupted communications during critical war operations in the Ukraine to literally control the outcome of military operations should chill anyone aware of it to temperatures close to that of Spacex rocket fuels on the launchpad.
Is there even any reason to doubt if he did it to the Ukrainian military in a life and death struggle he wouldn't do it do you over whatever trifle or financial gain he decided to take advantage of? He's already proved he's willing to cost human lives by manipulating the service he provides that certainly have an expectation of being free from manipulation, and not even for money, but just out of personal preference. He has no ethical problem with using your use of his products against you. I'm confident all corporate ISPs are equally mercenary, which makes Musk's actions typical of corporate profiteering. They certainly don't deserve my trust, and I wouldn't want to be utterly dependent for anything necessary to life on any of them. That's just the power Musk seeks with X.
Thanks!
