That’s an immature argument. “If you don’t like guns don’t buy one.” “If you don’t like abortion don’t get one.” Maybe we could think a little deeper?
One of the reasons the internet is so centralised is due to network effects. I have a facebook account because everyone else has one and it’s difficult to maintain a social life and a family life if I exclude myself from that space. I can choose not to drive a car, too but again that would make life much harder for myself. Perhaps we could subject these businesses to some basic standards of accountability and oversight and put the public interest ahead of private profit once in a while.
Given that they can rewrite their T&C or sell to facebook at anytime avoiding practices you dislike isn’t practical.
There are toilets that analyse your waste and send the results to your doctor. They ID you by scanning your anus since everyone’s anus is unique. Maybe one day the results can be sent to your kitchen and your fridge and airfryer can deny you access to unhealthy foods when your toilet tells them to.
