What’s the real reason for inside big hate?

I made an inside big for my very first build without knowing the game and everyone would just talk so much trash I stopped playing that character and made a shooting big. Now that I’ve played with it, what’s the point? I can set screens, stand in corners, cut and I get less boards, less assists all so I can watch the team miss every single shot and still not pass the ball? I get so heated I start forcing shots I know I shouldn’t take and I’ve actually started quitting games to stop wasting my time. Not trying to argue just want the honest truth about inside bigs because it’s obviously not clogging the paint.
