I can’t imagine how quickly they would be laughed out of a court with the argument of “you can’t split up our products, you see, the icons are all thematically the same!”
I don't think the parent meant this literal situation to work out.
It's more like building a passive perception of belonging-together over a prolonged period of time, where this is only one step of many, resulting in a subtle shifting of the framing when the discussion happens.
According to this guy's various interviews over the last few months he's trying to integrate a lot of G-Suite services together into a single offering, so it won't just be the icons that are the same. Who knows, by the time the antitrust case comes close to any sort of conclusion they might actually have a single product that can't be easily split anymore. He's even trying to add in "anticipatory experiences" (his words)[1] that make the product feel like it just gets the work you're trying to do. This obviously plays directly to Google's strengths as an engineering and ML powerhouse, and who knows maybe that'll be an argument they can make too.
