Even "legit" firms are
stealing from you. There is absolutely no shame in this stuff. None whatsoever. I turn off almost every tracker, ad-watcher-thinger, etc. Location tracking and what not is disabled. I use ad-blockers. I refuse anti-virus of all flavors. Anything unnecessary on my devices that can spit something out—and has an off switch—is off.
And yet I still feel the eye peeking over my shoulder.
If you want privacy, you'll have to turn the electronics off. And even then, Amazon wants a drone over your house 24/7.
