It seems highly unlikely that someone who made the effort flashing Libreboot to their laptop or buying a librebooted laptop from a supplier, would install proprietary software (Matlab) on their laptop because that misses the whole point.

Making some performance concessions and receiving something wholly libre in return is fine for the target audience.

Maybe they are ok with proprietary software in a ring3 user mode context, but prefee open software on the lower cpu ring levels?
