Epic Games took apple and Google to court, claiming that the two companies violated antitrust laws. Google seems to have a better chance of winning in court than apple. On Thursday, Epic Games filed lawsuits against apple and Google, accusing the two companies of imposing a 30% sales sharing fee on developers by taking advantage of their monopoly position, which is too high. In addition, they have set various restrictive policies to obtain various benefits for their businesses. < / P > < p > smartphones in most parts of the world are bundled with Google play app store or app store. It is more difficult to prove that play violates the monopoly law than app store. Apple requires all apps to be installed through the app store, and Google allows phones to be installed from other app stores, a policy that may help Google refute monopoly charges. < / P > < p > Google encourages mobile phone manufacturers to set the play app store as the default option, but when users download apps from other places, Google sets a security barrier. Nicholas Economides, a professor of economics at New York University, argues: “it’s certainly harder to accuse apps of being anti competitive by allowing apps to download from other places. Apple is different. It’s extreme, and there’s no alternative download source. You say it monopolizes, which is a strong underlying reason. ” < p > < p > Google spokesman Dan Jackson Jackson) responded that most Android phones are sold with multiple app stores, and users can also enter the app if they pay from other places. Moreover, Google does not force developers to set purchase options in the app (30% sharing fee is required); Google also allows customers to purchase from outside the app, so as to avoid the sharing fee. < p > < p > Shili Shao, an antitrust expert at Yale University, believes that “Fortress night” is off the shelves from the play store and leads users to other app stores. It has done a good job financially. Epic Games accuses Google of monopolizing, and it is more difficult to establish it because Google’s policy is more relaxed. Many apps have long been used to charging Google, because apps sell ads with Google adware, and Google shares 40%. Apple has no such relationship with developers, so they can’t compare. In addition, because of the existence of advertising business, Google can also appease dissatisfied developers in a unique way. < / P > < p > for the 30% share fee, Google refused to make concessions to Epic Games, but it agreed to give preferential treatment in terms of sponsorship and cloud services, but Epic Games refused to compromise; Activision Blizzard accepted such a proposal.
