Google is undercutting everyone in the mobile OS market. What once was a varied market died completely because nobody could compete with Android's "it's free if you agree to preload a bunch of Google apps" (iOS isn't really on the market since its Apple exclusive, LG can only reasonably choose Android). Google makes all that lost income back because this creates a monopoly for the Play Store, and massively helps other Google services.

Not really textbook examples, but that's because the textbook example of selling at a loss to kill all competition and then raise prices is illegal in most cases
