Regarding Netflix and Apple, the answer is "it depends". Cases are determined on a case-by-case basis.
Not sure we disagree (?). My understanding is that Google has a practical monopoly on search. This is not illegal in and of itself. Anti-competitive practices that leverage its dominance in search, however, would likely run afoul of EU and US antitrust regulations. (I'm not an attorney, and My understanding of antitrust law is at the level of layperson. )

So does that mean that Netflix shouldn’t have used its dominance in DVD rentals to get into streaming and just die when another company did? Should Apple not have been allowed to use its dominance in the music/media player business to get into the smart phone business?
Antitrust was traditionally used when a company kept other competitors out. How is Google stopping another competitor from creating a search engine? The fact is that no one is forced to use Google. People can just as easily type bing.com in their browser as google.com.
In fact, the dominant desktop OS, doesn’t have Google as the default search engine and thanks to a consent decree - at least in the EU - Google cant force manufacturers of Android devices to make it the default search engine.
If Microsoft wanted to outbid Google to be the default search engine on iOS devices it could.
