Does anyone have any cats that have lived long on friskies/fancy?

On TikTok, there were tons of videos in the cat community explaining how bad Friskies or fancy feast bad for your cat. There was this lady that said something about how these foods give them cancer. My cat is three years old and she adores friskies/fancy in the mornings and purina cat chow at night. She will not eat any of the high-end foods, and believe me I tried. I was just wondering if anybody had any successful stories with Friskies and fancy feast.
