They’re saying it’s a bad thing because they feel the risk of engaging in negative behavior with the hardware (which some people will only get once there is a positive use such as Torah) outweighs the benefit of having it for positive purposes.
And the risk of getting hit by a car when crossing the street outweighs the benefit of it when I’m doing it for recreational purposes… and yet I don’t think the OP would ever say “don’t cross the street unless you’re going to shul or work.”
