At least something good came out of Apple-Google rivalry.
In the case of a monopoly a potential corporate rival gets bought and shut down, or locked out of a market, or has their price undercut until they go out of business and then the price goes back up even further to compensate. Basically the consumer loses.
So corporate rivalry, no matter how fierce, is great for the consumer as long as both are forced to fight fair.
Mentioning monopolies in the context of the benefits of competition doesn't seem irrelevant to me, quite the opposite, and perhaps as a result I didn't immediately jump to the conclusion that it was an attack on Apple or Google or anyone else.
