When kids do better after they move out is that due to good or bad parenting? Please read details.?

My daughter didn't graduate high school, in part due to failing a semester of classes due to surgery. She talked back some, in part because I encourage thinking for yourself and would explain why I made rules. She moved out at 18, which I talked about waiting being better but her decision. She has flourished. Pays her bills, never borrowed $, no debt, cooks mostly healthy meals from scratch, exercises. budgets well, shops wisely, respectful, kind, compassionate, plans for future schooling, good relationship with boyfriend. I see this as because I taught independence, responsibility, budgeting, good character, etc. Someone heavily implied she is doing better now that she's on her own because I'm a bad mom.
