Not just the company, but other researchers and peers as well. This seems kinda like the point of including it with the publication, doesn't it? What's the value of the study of it can't be evaluated or peer-reviewed with the data present?
In my field, most studies are peer-reviewed without review of the data itself. The study was conducted strictly according to best practices guidelines, so we are not afraid of peer review. We are afraid of the suits coming in and making a fuss because they're big and have big money while we're small and penniless.
