My practical point is that Microsoft chose this particular solution not as the 
best way to solve the issue of booting
known-good code but as a way of impacting Linux and it whole concept of 
software freedoms.

I don't think anybody in the Linux community should be supporting this 
SecureBoot "solution" in any way, shape or form.
