CEO Satya Nadella acknowledged a strategic error in discontinuing the Windows Phone during its peak popularity. Bill Gates, co-founder of Microsoft, identified his greatest mistake as failing to dominate the mobile space, which allowed Android to take the lead. Gates attributed this failure to his mismanagement and antitrust challenges that hindered Microsoft's growth. Android, acquired by Google in 2005 and launched in 2008, is now the world's most popular operating system, holding a market share of 45.53%, compared to Windows' 25.36%. Gates conceded that Microsoft's missed opportunity in the mobile sector could have positioned the company as a leader. Rich Miner, co-founder of Android, criticized Gates for his misplaced lamentations regarding Microsoft's mobile missteps.
