Hogwash. Corporations use GPL because it saves time and furthers business needs. However, many/most/some corporations ignorate the strictures on the use of this intellectual property and this is wrong. Corporate compliance with the license on the GPL will not impose a burden that obviates the benefit. What it may do is force the individuals or management consultants at a particular corporation to coordinate with internal attorneys when using other people's work. Which they would do with any externally licensed IP. Yes, it may encourage a bit more NIH mentality, but it will be just as wrong.
