I sort of agree.
The biggest problem is simply that the large fins create too much drag in a continuous current, and the bettas wear themselves out trying to get to the surface. Because bettas need to breathe air periodically, they eventually drown.
Fin rips and other injuries are further risks of a constant water flow.
However, you can break up the water flow, creating "high flow" and "low flow" areas of the tank, and the betta will likely love it. My bettas periodically swim right under the flow of their HOB filter (which has been turned down to about half strength), playing in the bubbles.
I make the difference by having a heavily planted tank with driftwood as an extra baffle for water flow.
