The main criticism (IMO) isn't really the work itself but how it's handed down as wisdom. It wasn't really cathedral==proprietary and bazaar==open source. In fact it was about cathedral vs. bazaar in open source software and that story is more complicated and comes down to "It depends." There are certainly open source projects that have more of a cathedral aspect whether because of benevolent dictator model or, more recently, a strong commercially-oriented foundation. But there are also areas that look more like a bazaar which have some advantages with respect to innovation but can be... messy.
