How is that even in the same category? Google does not force you to install Chrome in order to use Search.
Both cases they're abusing market power in one category to compete unfairly in another market. Apparently this is called "monopolistic leveraging" and is a somewhat unsettled area of law in the US. [0][1] Here's another example. Amazon using its market power as an online marketplace to benefit in both the logistics market and its own-label goods market. [2] By not allowing anyone else to advertise on its front page,…
This is vastly different from advertising a product in the company website. Amazon got caught peeking into their own partners data, then leveraging that knowledge to unfairly compete with them.
> By not allowing anyone else to advertise on its front page, it could also be said that Google is practising "Refusal to deal", which is also forbidden, although I admit that case is somewhat weaker. [3]
Again, not the same. "Refusal to deal" means that Google would prohibit Microsoft from advertising Edge, their Chrome competitor, in their ad network, which is not happening.
But it's worth noting that Microsoft does the same with Bing and Edge, displaying a modal if you are using any other browser. They also got caught displaying large banners in the Chrome download page, which I personally think is even worse [0]
