Recently, the U.S. Department of Justice joined forces with 16 states (including California, where Apple is headquartered)A massive antitrust lawsuit was filed against Apple.In its complaint, the Department of Justice severely accused Apple of using a variety of means to restrict and undermine market competition in order to maintain the iPhone's monopoly, such as imposing high "Apple taxes", limiting Apple Watch to the iPhone, and banning cloud gaming.

However, according to media reports, some of the allegations in the lawsuit are not tenable in the eyes of industry insiders.Among them, the U.S. Department of Justice blamed Apple's monopoly for the failure of Microsoft's Windows Phone.

The U.S. Department of Justice believes that Apple's monopoly caused developers to fail to develop applications for the Windows Phone platform, leading to its failure.

However, industry insiders pointed out thatThe root cause of Windows Phone's failure actually lies with Microsoft itself.Its system cannot attract enough developers to provide a rich application ecosystem.

also,The U.S. Department of Justice also blamed Apple's monopoly for the failure of Amazon's FirePhone.The complaint mentioned that Amazon’s FirePhone, launched in 2014, was unable to make a profit and withdrew from the market the following year.

Industry insiders believe that the failure of FirePhone was also caused by its own reasons. For example, the customized version of Android system it used did not come with the Google App Store pre-installed; and the exclusive sales strategy limited the number of potential users.

besides,The U.S. Department of Justice also believes that HTC and LG’s withdrawal from the smartphone market is also related to Apple.It ignores that Samsung’s dominance in the high-end Android phone market is the key factor.
