Ok, last one. :) You've really just made a mockery of the ideology of competition haven't you? In fact, that is what corporations do. There's an awful lot of highly concentrated market power lying around for exactly that reason.
Would you please not use HN for ideological battle? At the point this stuff gets generic, it gets predictable, and therefore boring in HN's sense of the word.
For this reason, we should encourage corporations to form cartels to avoid getting taken advantage of by disloyal consumers.
