The entanglement of Google with Amazon and Facebook and Instagram is very clear on my phone - after the deep freeze of "Winter Storm Uri" hit Texas, many of us started restoring our emergency supplies and building a stockpile of fuel and emergency food. I in particular looked at emergency battery units (the size of a 12-volt car battery or larger, and some of them come with a solar charging panel). I'm seeing tons of ads from all of those battery companies come through my Instagram feed now. So Google and Facebook are paying close attention to my browser activity. I need to remember to use FireFox more, it has a "box" to put Facebook in as far as sharing my browsing history, but I don't think they have any restrictions on Google.

P.S. I haven't decided which battery backup to purchase, but am leaning toward a solar recharging one that doesn't cost the moon.
