Apparently online advertisers are pretty upset over some of the new privacy features being built into Apple's new web browser Safari 11 (which comes out with their new operating system High Sierra later this month).
From the linked article from the Mac Observer:
In a letter obtained by Adweek, the advertisers claim Safari 11 will “sabotage the economic model for the Internet.”
This is what happens when we allow companies and advertisers to profit off of our personal data. They get used to having access to it and before long they start considering access to our personal data a right. Then when Apple introduces new privacy features to help us protect our personal data companies and advertisers start coming unglued because Apple is going to "sabotage the economic model for the internet."
