Again, they get paid a cut of Google's ad revenue from Safari users. This has one impact on Apple's design choices - Google remains the default search engine.

Notably, this hasn't stopped Apple from introducing multiple anti-tracking technologies into Safari which prevents Google from collecting information from Safari users.

If I open up a new tab in safari it tells me that in the last 30 days Safari prevented 109 trackers from profiling me and that 55% of the sites I use implement trackers. It also tells me that the most blocked tracker is googletagmanager.com across 78 websites
