There are actually two problems here:
1. Bing allowing malicious ads
2. Edge not marking malicious sites
Problem #1 has nothing to do with Edge (other than Edge using Bing by default) and I’m sure Google may let malicious ads through from time to time.
But problem #2 is entirely Edge.
> The malicious URL that Bing is happy to promote can’t fool Google or Firefox. When I simply type the above URL into my Firefox browser I’m faced with a bold red page declaring “Deceptive Site Ahead” completely with details and an option to go back.
The recommendation to stop using Edge to download Chrome is indeed wrong though.
