Here is why more needs to be done to protect our privacy—primarily by us, but with Government’s assistance. Below is an example, quoted from a bulletin board I follow. The author is talking about an investment during a time of coronavirus disruption of supply chains, but the subtext should be obvious.

They don’t build physical widgets in Wuhan that might get hard to obtain…the ad biz will probably keep on rolling.
We just bought 2 new Android smartphones and 1 new Android tablet. Coming from a dumb-phone flip phone and a Kindle.
Google [Alphabet, which owns Google] OWNS that market. You cannot even download/install an app without having a google account. And every time you do something, Google prompts you to set up a payment method. No way to say “Hell no, never.” The choices are: google play card, credit card, debit card, and “skip for now, maybe later”.
So, clever me, I created a dummy google/gmail account. And logged in so I could install some free apps from Google Play. Fine.
But within 2 days it somehow associated my wife’s gmail account with the Android tablet. And she has NEVER touched that tablet. Now every time I go to use it, it asks me which account I want to log into—the dummy account or her account.
Google OWNS that market.

Near as I can figure out, her name is on our Amazon Prime account. And our Sony Bluray player and our Roku smart TV are both registered to Amazon Prime Video—so obviously in her name.
Now, we do not get cell phone coverage at our house, so all our external internet network access goes through our internet ISP. And the way that works is that, to the internet, every device in our house has the same IP address.
So something managed to figure out that her gmail account was associated with our external IP address, and also that same IP address was associated with the Amazon Prime Video account, and that her gmail account is accociated with that Amazon account. Therefore every device in our house that contacts the external internet has some sort of connection to her gmail address.
At home, the Android smartphones and the tablet can only access the internet via our internal network, on WIFI, since we get no cell coverage. So if somebody puts all these pieces together it is easy to figure out the connections.
Google managed to figure it all out. Took them 2 days.

Heads up.
