Yeah sorry I was a little careless there. For the cheeses we were sourcing it didn't matter, and for most of the raw milk cheeses they are done that way out of tradition and because the process is reliably safe enough.
For some unwashed aged cheeses it does truly seem to matter but those the production is so closely tied up with the local agriculture, aging in specific natural conditions etc it's really not a process to try to emulate in your cheddar at your dairy that averages an outbreak every 18 months like the one in the article.
I'm a big fan of cheese and have researched this a bit. The consensus seems to be if two cheeses were made with the exact same process except for using past/unpast then you might be able to tell a difference (especially for younger cheeses) but one isn't necessarily better than the other. Over the years cheese makers have learned how to get the best flavor out of the base milk. So a pasteurized brie will be just as good as an unpasteurized brie but made slightly different.
I've tried doing taste comparisons between past/unpast but there's so much variation for even the exact same cheese that I've never been able to detect a meaningful difference.
