> scammy ads plastered everywhere is what I'd expect from Google products

This won’t fit with the manufactured popular understanding, but at the current time, Google protects you from fraud and scam better than anyone.

I have been unfortunate enough to be scammed recently from a bing search result (ad). (It was a new computer and I decided to use Edge and bing was the default search).

Apple, Microsoft etc. are rookies in this game. Google just has the benefit of experience and hence is much safer now than anyone can ever become in the near future. Because of this, scammers are much more likely to target other platforms… which happen to be Apple, Bing, Facebook etc.
