Most of what I was able to find online are issues around getting a digitally signed boot loader. Linux distros needs to pay Microsoft for having that "out of the box" experience. Microsoft is a CA in this case. However, in bios I can load any key so in theory, Fedora or any other distro could distribute their own key which users could load and no longer depend on Microsoft.
Of course that's not very user friendly.
