Reminds me of the practice of Translations.com / Transperfect, one of the largest language services providers. Their HR policy is to not allow employees to name the company in any online space, social media or otherwise. So when you see staff on LinkedIn, for instance, their employer will invariable say "Leading language service provider" or similar. These seem to be completely unreasonable policies, to me, that in effect are demanding that basic facts are ownable by the company.
