"No evidence suggests that Google coerced Apple, Mozilla, or any other browser developer into adopting a design that includes a single default search engine"
Do you really have to coerce Mozilla when the money you pay them to keep your search engine as the default is basically their main revenue stream?
Do you really have to coerce Apple when in 2021 alone you paid them $15B to be the default search engine on Safari?
Can other search engines afford to pay so much money to these companies to be the default?
When the sums you pay to get a privileged treatment are out of reach for all of your competitors, you are doing coercion.
"Requiring Google not to compete vigorously would turn competition law on its head"
What are you competing vigorously for when you already own >90% of the market? Total annihilation of the few remaining competitors?
"Forcing browser developers to ask users if they want to use an alternative search engine will make the browsing experience worse. If people want to try other search engines, they're free to do so"
First, who established that any user experience alternative to yours is worse? Your marketing department?
Second, who said that proactively asking people what product they want to use (and asking only once) makes the overall user experience worse?
Third, how are non-tech people supposed to know that search engines alternative to yours even exist, if every time they open a browser on any device they only see your search bar? Let alone knowing how to change the default engine in their browser, let alone installing extra software on Android just to have the default search bar replaced?
Google's arguments against users choice are exactly the same as Microsoft's a decade ago, when they were eventually forced to ask Windows users which browser they wanted to use.
Microsoft executives back then were all like "it'll make the user experience worse / it'll confuse users / people will keep using IE anyway / blabla"
Surprise, the browser choice dialog turned out to be a big nail in the coffin of Internet Explorer.
It turned out that most people didn't even know about the existence of browsers like Firefox and Chrome unless somebody asked them if they wanted to use them. It turned out that many people actually liked them better than IE and they never came back.
And that's what fair competition is all about: giving everyone the same visibility, and letting users pick what fits them best.
Google is using the same argument as Microsoft ten years ago because it's afraid of competition. Because it's going to fight hard to maintain its monopoly. Because monopolies can be sustained only when you don't give users a choice (see Facebook and user tracking consent), or when you hide the choice away from users.
Even if it comes to the cost of contradicting their own position a decade ago - when they argued against Microsoft and its "monopolistic practices" because the browser choice dialog would have benefited Google's (still infant) Chrome browser.
