Because all the companies producing the several parts involved did absolutely no r&d and they got information on how to produce all those batteries, cpus, glass, radios, sensors, etc from aliens. Every company does r&d and manage just fine with non obscene profits on each product. Apple and Samsung create artificial scarcity with lawsuits. They probably spend more on legal than r&d.
