> Secondly there's the ethical point, that RH have chosen overall to give aid to a Microsoft-inspired and Microsoft-favouring system, and to make themselves hostage to that, instead of unequivocally fighting against that.
You make it sound like treason, which is a ridiculous concept when applied to this case. Working with standards that MS also works with and has influence over is not an "ethical" challenge. Fedora and mjg59 have already stated their constraints, they are willing to work on secure boot on systems where key management is available to the end user (even if it isn't as user-friendly as they would like) and are not working on secure boot for systems which are boot locked, without key management (Win8 ARM).
> All in all, I'm afraid it's difficult for me to believe that there isn't an ulterior motive.
This isn't a matter of faith, it's a matter of reading the very open dialog that exists. The fact that you see ulterior motives probably reveals more about your own thought process than illuminates the discussion.
