You are right. At the very beginning, Safari was innovation and Jobs wanted the web succeed. I meant of course the period when webkit was the only browser engine allowed and Apple claimed the reason was they wanted security etc. Now it is clear that even then, the true target was web capabilities and the hindrance of them via webkit control. Now that they use iOS to disallow these modern web capabilities in competing browser engines too, they admit to their true target of the past 10 years or so too.
