Why not just chainload grub?

That is a horrible FAQ entry and could really use some further elaboration. The way the FAQ explains it undercuts the GPLv3 and inadvertently provides FUD for detractors to throw around.

Their secure boot specific FAQ doesn't say anything like that and specifically references Matt Garrett's documents on the matter. Fedora obviously doesn't think there is anything wrong with signing a GPLv3 GRUB2 and the FSF links to it as their explanation.

There is another thread along the same lines here https://lwn.net/Articles/504015/. A vendor shipping a signed, boot locked, GPLv3 GRUB2 would be a pirate, distributing without a valid copyright license. There are many way ways to resolve that, recalling/refund/RMA of hardware, a firmware update, etc where disclosing the private signing keys is the least likely method to achieve compliance, although it is a valid one.
