I'd consider Webkit pretty useful.

clang too...

Webkit was derived from KHTML, which is LGPL.

However, the bulk of modern Webkit is BSD 2.0, using LGPL libraries. Apple (and the other contributors) were under no obligation to contribute that bit.

Don't say forget CUPS

WebKit has been open sourced 10 years ago. CUPS is even older than that. What has Apple been up to recently?

You know, you could name projects instead of clicking the upside-down arrow. Clang comes to mind (not LLVM). Google and others contribute heavily to clang, but Apple started it. They deserve credit for that. Anything else?

Vikram Adve and Chris Lattner started LLVM at the University of Illinois in 2000. Only 5 years later, Apple got involved and hired Lattner.
