User control of the browsing experience needs to be the default. When I tell my browser to go to a page, it should not be “normal” to load content, assets, and scripts from dozens of other sites. The practice is a dishonest hijacking of the user’s experience, and hogs a lot of bandwidth for functions which the average person does not want. Those who vocally want trackers, beacons, pop-ups, are a vast, vast minority.
Sure, one can install a browser plugin such as noscript and manually set what is run for every site. But I think it is better practice for site administrators and content creators to not send our browsers anywhere else without explicitly getting our permission.
