Ok, I guess we won't see eye to eye. Let's apply your argument to the "big guys": are you saying it's fundamentally fair for Amazon to poach sales data from marketplace sellers, then use that to develop identical competitive products and undercut them? By your definition, that's not a bad thing, it's "ownership": they own the marketplace, they can do what they want, right? Those Amazon sales pay the server fees, right?
I'm sure you will find many reasons to convince yourself why this doesn't compare; and of course you would be right. It's an analogy that applies in concept (perhaps even just tenuously) but not in scale.
