Some will enjoy playing with it, but not living in it. It's tiring for them. They just weren't designed for it. One of my males (RIP) used to love playing near the filter, he would rush into it and tumble over and over. More regularly though he avoided that area of the tank. This was the lowest setting on a small whisper filter, which caused a lot more current when I had the tank divided with some mesh - the current was on one side and he didn't have anywhere to go but hang out against the front glass where it pushes him. Eventually I put some plants under where the water was falling and he swam around the entire space more frequently.
These are bettas that live in ponds - not salmon who swim up river. They've adapted to live in such water. Regardless of how far back our domesticated bettas are related to the wild types - their design has just been made worse by the fact they're bred to have mostly large fins.
