I've been on a tour of a distillery. They open ferment and all but encourage the visitors to poke their fingers into the mash. It's no problem for them as they will distill the mash.
One episode of Michael Jackson's Beer Hunter had a brewery that open fermented. They used the wild airborne yeast to ferment. There was open windows and cobwebs everywhere. They said they were afraid to clean; didn't want to disturb the wild yeast.

Breweries not brewing lambic styles use yeast that forms a thick head on top that doesn't fall back into suspention which protects the beer.

They used to just have a video that showed just the fermentation time compressed. If you don't have the full fifteen minutes to watch, skip to the end.

the "i opened my bucket is it now infected" posters should watch this video.
I think this is somewhat typical for Belgian breweries.
A local brewery or two do this, not completely open, but just with a lid over it (bit like a carbage can type fitting). The room is kept is clean and there are fly killing things and flaps over doorways to stop too much airflow.
And the yeast does drop out of suspension, but they top skim it usually before sticking it in a bright tanks.

Only one of the trappist breweries still have open fermentors. Can't remember which one.
Jolly Pumpkin in Michigan reportedly has open fermentors.
