I know I'm preaching to the choir here...
Privacy isn't something that corporations or the government gives to you. It's something that you have to create and protect for yourself.
Installing a meta app on your phone comes with an agreement (which you read, right?) where you give up all of the privacy of your phone in exchange for apps that make you feel bad about your income, life and relationships while also being misinformed and angry about current events. It's such a terrible deal where you lose everything in order to send pictures to your friends slightly more efficiently (Signal Stories work just as well but are end to end encrypted)
It's like letting a narcissist live with you who constantly berates, insults and lies to you in exchange for them occasionally telling you how your friends random people that you really don't care about are doing.
