I think it's a bit disingenuous to conflate this with hijacking. Also, I do not see the banner when I view the page in Edge. Displaying a banner outside of the page in a separate window (as is indicated in the article) is definitely not hijacking in any sense of the term.
> There's debate among those discussing the banner online whether the ad consists of code injected by Edge into Google's webpage, which would make it detectable and removable as part of the Document Object Model.
> It has also been suggested that the ad may come from Edge as an interface element that's stacked atop the rendered web page. We believe this is the case.
So technically not.
The fact remains that by displaying that "pixel occupation window" or wtf ever you want to call it instead of intrusive spyware, you are proving to me that you are desperate and if you would resort to this you are not to be trusted.
I guess that's not really relevant if you are in the boat that is using Edge in the first place.
