You think Apple should be punished for creating a vertically integrated stack? Setting aside private APIs as I have no idea what Safari does or doesn't use (although vast portions of it are open source, enough that you can compile modern versions of WebKit and "upgrade" the ancient WebKit on PowerPC Macs), another browser could be just as closely integrated as Safari. Obviously, the cost/benefit ratio is awful for Mozilla and Google, so they won't, but why should Apple cripple their own software? Safari's development costs, as part of MacOS, are funded by profits from Mac sales. Safari is deeply integrated with MacOS which is in turn deeply integrated with the Mac. In my opinion the whole point of the Mac is this vertical integration, and the main value-add of Apple's sphere. If you don't value that, there are cheaper options where cheaper and more flexible software is available. To me, an anti-trust suit would make sense for Safari on iOS, where Apple has locked all competitors out (in practice). Saying Apple should be fined for Safari because it's more integrated and efficient and that's not fair to Chrome and Firefox seems a bit silly, especially given (desktop) Safari's relatively small usage numbers. All IMO of course.
