Wouldn't you assume that closed-source products would generally have a competitive advantage against open-source products? Especially for products where most of the contributions to the project are from the company selling it. With closed-source you have to worry less about people simply selling copies of your design without having to have invested in any of the design process. Competitors also can't as easily include your design improvements into their products. And, there's definitely a cost associated with sharing internal designs.

That only sounds like an issue in markets without healthy competition, which ideally shouldn't exist either way.
