All the big techs are stifling competition in many markets by offering their product in those markets at or below cost and supporting those losses with money that comes from elsewhere in the company. Look at music streaming: Spotify is the only big service that is only in that market. Look at consumer storage: Dropbox is the only big service that is only in that market. If tech behemoths didn’t exist, there would be much more active competition and thus technological advancement in those markets. They also buy start-ups in emerging markets at a breakneck pace.
