The title of this article is deceptive clickbait.[1] The problem has nothing to do with the Edge browser, it has to do with search results returned by Bing, which happens to be Edge's default search engine. If you have a new Windows 10 PC and want to download Chrome, how else could you do it besides "using Microsoft Edge to download Chrome"? So "stop using Edge to download Chrome" is not useful advice. Better advice…
It's not irrelevant. Bing is what Microsoft chooses to use a default search engine. Edge does not warn of a malicious website. Chrome and Firefox do. This has everything to do with Edge.
As I noted back in 2017, Edge flagged the destination site as malicious, Chrome did not. Warning on malicious websites is, in fact, done in Edge. But as with Chrome and Firefox, it doesn't catch every one of them.
