I honestly think it’s everyone’s responsibility to make their job as hard as possible. Use providers that prioritize privacy and that are located outside the US. Don’t ever use telephony or sms always use end to end encrypted services for conversations, leave your phone at home or turn it off, use a rom without Google play services. Really drive them nuts and use cash for most purchases. This by no means stops everything but it makes it harder. You can’t stop all data collection but you can reduce it and every reduction helps.
As someone who lives through the height of the mall era I’m sad to see the go personally. However before online shopping it was sort of a pain in the ass. Not only did you have to go to the mall for clothes shopping sometimes you would have to go to more than one. I remember school clothes shopping would be a multi day affair to buy some jeans and shirts and a pair of shoes. If the mall didn’t have the store you needed you would sometimes have to drive really far to go to that store. If the mall didn’t have what you needed you were sort of SOL. So when online shopping started to provide anything you want in a few clicks it was not just the hard to obtain stuff people bought it was everything else too. But it’s sad so many teenage sagas played out in malls for me. Friendships were solidified and dating occured there. It was a place you could hang out for a few hours with no parents and navigate teenage social life. I am sure teens will just do something else but it holds a special place in my memory.
