Well, Safari&#x2F;Chrome&#x2F;Android browser&#x2F;etc is a result of an open source project Apple adopted (KHTML), expanded and developed way beyond the original code. And while Webkit couldn&#x27;t merge back into KHTML easily, it became the basis for a full blown Open Source engine of its own with tons of adoption.<p>Also LLVM. Apple heavily funded work on it, and it&#x27;s now used by everybody who&#x27;s anybody in the industry, from Google to MS.<p>Apple just doesn&#x27;t care to go into much community development by committee (bazaar) because they have their own (cathedral-like) agenda to follow.
