Anti-trust is much more about a company having a dominant market position such that users are locked into their products no matter what. Google has 92% of the global search engine market. They pay Apple $15 Billion per year to keep their search engine the default in Safari. They have 65% of the browser market, tripling Safari. Microsoft are locked into Chromium with Edge, despite being Google’s largest competitor in search. They also have the largest share of online ad revenue at 39%, doubling Facebook’s 18%.
Apple does dodgy shit too, but they don’t dominate any one market since the demise of the iPod. You’re only locked into their software if you buy their hardware. Which still isn’t right, but it’s nowhere near the level of influence that Google wields.
Edit: Don’t even get me started on Amazon, which also deserves a higher spot on the list than Apple with their domination of eCommerce. 37.8% compared to Walmart and eBay both at 6.3%
If you need more ammunition they recently also changed it so all links in Outlook opens in Edge even if it's not the default browser. You have to go to settings and find an entirely separate default browser setting to stop it.
