You're right. They don't provide graphics card drivers, but they "do" provide some (less important) drivers. I can't find a link (slow internet connection right now), but see here for example: http://www.canonical.com/engineering-services/oem-services/w...
Anyway, my point was that if Linux guys prove to be costly, they'll be dumped or neglected. It's bad for open source guys, it's bad for OEMs (they get worse deals with Microsoft), and it's bad for everyone other than Microsoft. So, if you think SecureBoot is bad, make your case like civil citizens without inducing cost to others.
That page is about "drivers" in the sense of "reasons that drive the decision to ship Linux", not hardware drivers :)
I don't actually support the kind of crude protest measure suggested by the article (although I doubt a non-negligible number of people will actually carry it out in any case), but drivers really aren't the issue here.
