While the fight between Apple and Meta may seem recent, their war started a decade back. It was not a corporate war but the war of ideology: free internet vs User's right to privacy.  since then both companies have kept fighting. The fight took an ugly turn after Apple released iOS 14 and 14.5, putting the final nail in the coffin for Facebook or Meta via its App Tracking Transparency Policy. this put a massive dent in Facebook's revenue- 10 billion dollars a year and Facebook stock prices dropped 23%. since then Meta has reported a decline in the users on the Facebook platform. the war between Meta and Apple for control over users' data has turned it into the ugliest ideological war in silicon valley.  This is the story of that war.
