Oh I know this brother because this is my profession but I choose to have targeted ads as opposed to non targeted ads. This has been a thing since windows xp days when Microsoft had enough telemetry data even then!
When I was searching for a sleeper sofa, I got many ads in the next day.
And to operate in a non-targeted ad configuration, most of the internet won’t work.
I tried to do this many years ago with PF sense and I ended up blocking my kid’s school so I had to disable the PFSense ad blocking component.
The thing is that I’m not sure why I would want to do this and what I would gain.
Yes I would get more speed on page loads but with gigabit internet and 5g phones, speed isn’t an issue anymore because we’re not in the 90s where we have to use dialup. Lol
Yes the late 80's early 90's when we had to have the desk top side plate off and master/slave HD's ready to plug and unplug to stay online. Back when there were less than a million users and all but 3 of us were hackers,lol. Do you remember Microsoft ME? I realized why they ended it once when I was reformatting a HD and hit the surge protector by accident. When I turned it back on it went into repair mode(check for errors) and ran for about 24 hours and rebuilt itself. I guess when MS realized that they thought it was best to end software that didn't need us to spend money.
