APUG has had at least one member who consistently uses and recommends to others using Nikon F5/6 bodies in matrix metering mode to meter for 4x5 color transparency shots. They are his light meters for sheet film shooting. I've seen several others recommend something similar here on APUG.
Mike Johnston has been around photography as a magazine editor, equipment reviewer, and writer for decades, but has never made a living as a shooter, and admits that he may not be cut out for it. He sometimes uses hyperbole to make his points, but anyone who's read him over the years will know that he's not what you'd call dogmatic or inflexible in his thinking. He also puts his prejudices up front, and has things to say worth thinking about.
If you read what he says in the article then some of the responses here either assume he's lying about what he's seen in studios, or that he didn't admit that he may be missing something in his approach to thinking about light meters when doing digital photography, which is what the article is about. It's not about film photography. It's about not needing a light meter when you have instant digital feedback when shooting digital.
