Why doesn't Safari have a built-in AdBlock?

Apple traditionally relies on user privacy, but full-fledged ad blocker in Safari never showed up. The reasons lie in the company's business model:

• 💰 Advertising revenue: Apple makes money from advertising in App Store And Apple News, so completely blocking ads is contrary to its interests.
• 🛡️ Security: The company is afraid that third-party extensions may collect user data (and not without reason - some blockers actually do this).
• 🔄 Ecosystem control: Apple prefers that users install extensions only from App Store, where they undergo moderation.

Instead of a full AdBlock in Safari there is a function Prevent cross-site tracking (Settings → Privacy → Prevent Cross-Site Tracking), but it only blocks trackers, not the ads themselves. Moreover, with the release macOS Ventura And Sonoma Apple tightened the rules for extensions, which made the work of many blockers more difficult.
