Are Google results good? I stop using Google years ago because of the garbage results (a lot of spam sites that were just serving data crawled from Github and other sites).
On top of that, Bing’s deep search feature has proven to be genuinely useful
Not because "privacy:", not because "tracking", but because malicious ads exist, and you'll click on one eventually.
This is even more true for less technical family members.
Those cycles are mostly earned back when you visit a link with ads (unless the search results are limited to ad free sites). So, it's still a net positive to have an ad-blocker.
This is a neat feature, I used browserosaurus for a similar behaviour, but also that means I have multiple browsers open, one basically for each profile.
Running those same specific queries now, the Google results are as bad or worse than Bing's results at the time, and Bing now frequently gets the results that Google did at the time. But my everyday experience is still that Google gives generally better results than Bing / DDG.
