Lynch, by the way, was an outsider in Hollywood and in the wider movie industry. He didn't make large budget movies nor did his movies bring in a lot of money. When he was promoting his last movie, he didn't even have money for proper advertising and had to rely on publicity stunts like sitting in a director's chair next to a live cow in the middle of Los Angeles to draw attention: https://www.youtube.com/watch?v=n9gVoSiXup0
His struggles were largely due to his refusal to trivialize violence or turn it into something easily digestible. Many of his characters (such as Dale Cooper in Twin Peaks) are highly moral and good-natured people who encounter incredible evil. This evil is depicted in an exceptionally disturbing way to amplify Lynch's message about genuine love, compassion and human connection. Lynch did not exploit or glorify violence. He presented it as something deeply unsettling to highlight its emotional and psychological impact instead of using it for shock value or cheap entertainment.
It seems like you are very angry about something you don't know much about.
