I've done networking for a really long time, but we can always learn something.
I use a vpn. With my own pihole that uses DNSSEC to a rotating variety of DNS providers (I think 5 of them right now), with about half of DNS requests blocked and about 70% of the remaining being served from the piholes dns cache.
I run several ad blockers covering 3rd party cookies, and anything malware related, to block what might leak from my browser.
I'm not looking to protect myself and my information from State actors, or even "big tech". I'd just like to skip that oddball sysadmin that decided that they like or don't like me and wants to figure out where I live and who I am. I'd prefer that things like my email, phone #, IP address with location and what I browse for and read is hard enough for any one person or smaller entity like a social media company to see and collect as annoying and as hard as possible, at a low cost and low PITA factor.
So far this has been a problem with just two online businesses. Chewy decided somewhere to throw a security "concern" flag when placing an order, requiring their equally mystified customer service people to wonder why they had to call me to approve an order. And Instacart does the same thing. Let's you log in, shop and after you order your order is canceled. They wanted me to upload my drivers license and a photo of my credit card to unlock the account, and that's a big fat nope.
Other than those two, everything works fine with the thing where google asks you to prove that you're a person. It doesn't do that with every search as described elsewhere. Just once or so a day.
