I’m against big business spying on me just as much big government but I guess the boat sailed on that a long time ago
It is an irritating problem. The best way I know to combat it can get slightly complicated and hard to keep track of. But all you have to do is set up accounts where you share little or no personal information including your primary cell phone. The biggest hoop you have to jump through to do is getting a cheap used, unlocked cell phone and purchasing a $3 a month "pay as you go cell phone plan" for "verification" and "account security" purposes. I give recommendations if anyone is actually interested.
