The Linux Foundation has a misleading name: it's essentially the Megacorporations Linux User Group. It wants whatever its member companies want. It does not really want to promote Linux or, say, enforce the GPL.
Indeed, and while I am mostly a user of commercial software, I appreciate the work that Stallman and FSF have placed on the GPL.
Whatever non-copyleft licenses allow for, it was already available via public domain and shareware like licenses.
Yes, GPL makes is very hard for certain kinds of business models like games or desktop software in general, however when people complain about its existence, most seem to blind to the fact that they only have Linux and GCC because of GPL, and clang wasn't around until 2007.
Had it not been for them, and most likely all commercial UNIXes would still be around.
I left that out to avoid opening a can of worms, but yeah...
If I was Linus, I might also avoid raising a stink because the Linux foundation does a few things that need to be done, and the damage it is doing might be less bad than what happens after discrediting it.
