While there are things that are difficult to do with bodyweight exercises, there are plenty of ways of upping the difficulty.
E.g. I benched ~150kg when I was doing powerlifting regularly, yet I wouldn't have a chance in hell of doing a planche push-up, or quite a few simpler push-up variations.
> only three of them can are usefull for athletic people
This, however, is a very strange claim. "Athletic" means an awful lot of very different things to different people. Someone doing gymnastics for example will typically be able to do a whole lot of things that most weightlifters wouldn't be remotely close to, and they need to to be able to do the things they train for.
Like planches. Or flags. Or L-sits with rings.
I could at one point do L-sits, and the guys at my gym looked at me as if I was crazy - most of them couldn't get close to lifting their legs to 90 degrees.
I've mostly trained with barbells, but it gets pretty tiresome to see people dismiss bodyweight exercises to totally - I could lift weights most people doing bodyweight exercises can't get close to, but they can do lifts and motions where I'd be starting basically from scratch.
To call them "limited" is pretty weird to me. People who do bodyweight exercises to a high level seems to have a more versatile strength. It's just different goals.
