Is it really an ad though? If you aren't using edge it's because you prefer something else, not because you don't know about it. Microsoft tries hard to maintain edge as the default.
It's not like this post highlights its capabilities or makes an argument for edge vs other browsers.
I mean, I get that it can be hard to find a good UI/UX, but I think I'd sill take a look at the Hindenburg Research report. I know they're a hedge fund that stands to gain from the firms they're short-selling loosing in value, which is questionable, but I'm unaware of them manipulating facts. I personally don't think it'd be comfortable trusting Opera/their owners, if they're willing to do stuff like this.
No shade, but it amazes me that somebody would think that people doing marketing for a product called "Edge" would not be aware of its (double) meaning.
