That particular case sees Apple setting the rules of the market, not acting anti-competitively. All the browser-makers successfully compete on features, as proved by the continued existence of multiple browsers on the App Store. Hell, Firefox can even afford to cannibalise its own market with two versions of Firefox (FF, and FF Focus). Furthermore all the big name browser makers sell their offering at "free". In my view, this makes browsers an outlier in any discussion of Apple's anti-competitive behaviour. It doesn't shut down the conversation, just takes browsers out of it.
