Section 3(a) says that you grant a license equivalent to the Apple
licence to third parties, section 3(b) says you grant Apple an
irrevocable licence to do whatever they want with your code.

I wouldn't call the 3(b) license "equivalent to theirs".

I see they quote Eric Raymond of "The Open Source Initiative" on their
web page - maybe SPI should retract his license to use the trademark
"Open Source" for that organization.
