This is what happens when innovation threatens dinosaurs. Phrases such as "predatory pricing" exemplifies a fundamental misunderstanding of how pricing works, or markets in general.
People forget the whole point of the market is to serve the consumer. The point of the market is not to protect the interests of old tech giants because they can't compete with free. They're willing to prevent consumers from enjoying the satisfaction that Android has to offer because they want money for doing what Google offers for free. By this logic I should start a search engine that charges $10 a search, then sue google for anti-competitive practice.
Everything about business is predatory. Every time a company releases a better product it is predatory to their competition. Offering an edge your competitors can't handle is kind of the point. If Google's pricing is so "predatory", why doesn't the competition do the same? Because they're ethical?
