This is TRUE.

This is FALSE.  Even modules for Asterisk MUST be released under GPL,
unless you obtain a license to release them outside of GPL from Digium.

This is also FALSE.  You MUST release both the module AND core changes
unless you obtain license from Digium.  I believe you are confusing the
"Linus exception" which is an exception for the Linux kernel explicitly
made by Linus Torvalds, allowing binary only modules to the kernel only.
