I think if you want the point of view of a corporation you should feel free to go read their official blog, press releases, etc. They have plenty of ways to spread their point of view that aren't people pretending to be individual commenters.
A corporation is a collection of people. A corporation doesn't have fingers nor mouth, and can't type nor speak. It is always a (series of) paid individual(s) who types and speaks "on behalf of" it.
Note also that "on behalf of" can only exist in response to some prior meeting (or deal) with certain members (board or employees) of the corporation who wish to push "its" policy.
