Does Safari phone home every time I access a website to cache my browsing habits so as to deliver me more targeted advertising?
No browser (even chrome) calls home on every page load. No browser has ever done this. Chrome simply syncs your history and bookmarks every X minutes, you can even watch it doing it. If you use chrome on multiple devices at the same time, you'll even get the exact time it did the sync.
Watch it with Little Snitch or Wireshark.
Apple has far less incentive than Google to violate someone's privacy, because their money does not come from advertising.
What would you define as a privacy invasion in this case? By using a Google site, you allow them to anonymously store info about you. The same applies to every single website on the internet. Any website owner can store the available info, which is your IP, location, browser, OS, and a few trivial bits of info about your OS (E.g if flash is installed, java, versions, etc). What part of this is a violation of your personal privacy when you are authorising them to do it?
iAds are not browser need, and they're not a major business, either.
So because Apple hasnt made a success out of their ad network, it means they are excused from being questioned on user privacy as well?
Google, on the other hand, relies almost exclusive on violating your privacy to stay in business
Dont be so ridiculous. Google relies on you using their services to stay in business. If Google was found to be violating people's privacy intentionally, it would kill their business overnight. All their business contracts would become null and void instantly, Google Apps would cease to exist, meaning funding for Gmail, Docs, Calendar and such services would die instantly.
to the point that they will literally hack your browser to steal as much information from you as possible.
Nice way to twist it. You and I both know (that is, if you actually researched before posting) that was an isolated incident by a rogue developer.
I refer back to the privacy issue Apple had in 2011 with caching of location data. Apple took a fair amount of time to fix it, there was even an app developer who was able to release an app to show you the data. It was exactly the same situation that Google had - an internal cockup by a stupid developer.
We're going round in circles here. The facts are clear though: It would destroy Google if they 'turned rogue', hence you'd be really foolish to even think it would happen down the line, let alone claim it's happening already.
Getting back to the webkit fork. People would have to be insanely dumb to think it would have anything at all to do with bypassing privacy, especially given that its opensource.
