I agree it’s a legitimate point and a debate worth having, but rule 1 of any genuine attempt at persuading others is to avoid alienating the very audience you want to persuade (in this case by coming across as jealous and vindictive and thus unreasonable).
Sorry, just to be clear: I assume Zed is trying to convince me and other non-corporations of a particular position. I don’t think Zed is trying to influence any corporations directly, and he’d probably say any attempt to so is a lost cause, whereas influencing consumers as a class is a roundabout way of influencing the corporation because it goes directly to your #2.
Regardless of how you feel about his tone, what he’s complaining about does happen quite a lot. He has a valid point that’s worth debating.
