I think that’s because of GPL-2, which had allowance (unintentional) for Tivoization, which is what Secure Boot is a form of from what I read. I might be wrong on that, though.
IIRC the first draft had the keys all controlled by Microsoft, with no option to use your own, and no option to disable it. Don’t think the GPL had anything to do with it directly, though it was people wanting to use Linux (and other systems than the one pre-installed) on their own hardware that complained.

GPL-3 fixed the Tivoization, though.
