I would definitely remove them. Yes, you'll always find people here for or against defoliation. Personally, I've had better yields since I started defoliating. The buds get thicker and the plant has better airflow. I've also tried growing the same strains with and without defoliation at the same time, and in the end, the defoliated ones always had more yield and were often healthier. Yes, in nature, plants don't do it, but you want more yield; in nature, the plant just wants to be pollinated, and in the rest of agriculture, plants are also treated like tomatoes, which are also defoliated. Good luck!
