How many times does it need to be explained?

Catching a Pokémon with a Poké Ball the normal does not capture them in the literal sense. When we "capture" a Pokémon in a Poké Ball the normal way, it's the Pokémon agreeing to stay and join. And Pokémon can leave their ball whenever they want. So yes, the guy from OP's image is totally doing something bad whereas using a Poké Ball the normal way is not, it's not a contradiction. If anything, an example like that guy should make that even more obvious.
