The complaint is likely to focus on challenges to Amazon Prime, Amazon rules that the FTC says block lower prices on competing websites, and policies the FTC believes force merchants to use Amazon’s logistics and advertising services, according to some of the people.

Relevant part of the article - they’re not going near AWS or the entertainment/filming side of things, just the retail side it looks like.

Even if Amazon loses every part of a lawsuit like this it won’t materially affect their bottom line, so the headline seems like clickbait to me.
