No, it says "the pop-up will appear even when Microsoft Edge is the default browser... The company is not targeting people who use Google Chrome and Firefox as default browsers."

I.e., it shows up for everyone, not just people who aren't using Edge already. They aren't specifically targeting Chrome and Firefox users; they are just also included in the group.

Can confirm that I never encountered this behavior and I have Edge (although Canary) as my default browser at the moment.
