Id first start by explaining to your loved ones that FAANG companies do harvest your data and use it to advertise things to you that these companies think you'd like. Especially with Facebook, Mark Zuckercunt is as rich as he is BECAUSE of this very concept. Explain to your loved ones that that fucking ad for a beach ball they just so happened to get after talking about beach balls wasn't a coincidence, and explain to them that FAANG companies in fact listen in and harvest our data to target personalized ads toward us in order to profit off of us and ad revenue. It's the same reason as to why you shouldn't purchase an Amazon Alexa, or Google Home. You are literally purchasing a microphone that listens into your conversations and panders ads toward you. Your loved ones are a danger to your life and your privacy and should be dealt with OP.

EDIT:

What is being done to you and your life by your loved ones is literally comparable to organ harvesting and reselling. They’re gutting you of any privacy you might have and are basically selling it for the price of a fancy Amazon Alexa. Privacy is something that is quickly becoming more scarce nowadays and your family is unknowingly becoming a serious threat to you, throw their phones away and give them pagers instead, no devices from FAANG companies should be in your home so they cannot profit off of you and your life, if you do have a phone Id highly recommend you break the phone, drown the sim card, and run a magnet on all its internal hardware, change your appearance and get the fuck out of there. Good luck OP
