"It's easier for them to track what you read on the web more aggressively and that's not very good."
That premise is right about Facebook but not necessarily with all iOS apps that have "in app browsers"
iOS provides two methods to provide an in app browser - the traditional webview where the parent app has access to everything you enter - but doesn't have access to your browser cookies from Safari, your bookmarks, history etc and the web controller which is basically a separate process running Safari inside your app. It looks basically the same except the app has no access to your cookies, passwords, bookmarks, but you do have access to all of the above functionality and any ad blocker you have installed.
I don't use the FB app for just that reason. I use the mobile site.
