I'm afraid that's not relevant.

The recent news pertains to a new release of UEFI, version 2.3.1, which
introduces "secure boot" as an optional feature (although one we would
not be surprised to see many OEMs enable by default).  Sure, GRUB can
boot under such a system - if you get it signed by an authorised key,
implying that you can't effectively install a modified version, or if
you disable "secure boot" in your firmware setup, which not only sounds
bad but it seems may well also impede dual-booting Windows.
