Another problem is that Facebook, Amazon, and Google get special treatment. There are explicit filters in WebKit (and probably mozilla) which allow special features for certain big-name companies. Also the App Store gives exemptions (e.g. VoIP notifications) to certain social apps. And most websites block crawlers but allow Google and Internet Archive. This IMO is a better argument towards anti-competitiveness. I absolutely get that there needs to be filters for certain privileges, but hard-coding them for big-name apps is not the answer.
