Someone on the comments for the article page made an interesting point, and one that I've seen happening for a long time.
UltraViolet would essentially be an artificial barrier to entry to keep the independent filmmakers from transforming the landscape the way that the internet has threatened to make major distributors nearly obsolete.
that's really what counterpiracy is all about, and ever has been. It's not about the grandma or 12 year old that downloads songs off Limewire or BitTorrent. It's about the huge number of recording artists that are making pennies on the dollar, if at all, from major labels. Both the successful artists, and the indie artists, who rarely ever sell enough albums to break even on the advances owed back to the record labels, have a strong incentive to go independent.
the same holds true for filmmakers who are stuck in a farm team system of film festivals, music video directing gigs, and other thankless jobs where only a tiny fraction of them might ever make it in the current distribution paradigm.
But if that changes, and digital theatrical distribution allows them a direct channel to movie theater exhibition, it's game over for the majors.
