Do you have any data to back this up?
User error is likely the leading cause - either not fully seating the lens to lock or inadvertently hitting the lens release button and unlocking the lens either immediately or just a little before an accidental lens release.
If you read more carefully you'll see that's what they're saying is the cause - the strap, the way it attaches to the lens, somehow allows the lens release button to be pressed easier - so yes, "inadvertently hitting the lens release button" is the cause. Some are saying the design of the strap increases the likelihood of that happening.
If it is true that the strap, while attached to the lens, increases the likelihood that the lens release button will be pressed, thus releasing the lens, and the body then goes crashing down on the pavement, then I personally would consider it a flawed design, especially if BR claims that the strap can be attached to the lens itself. Of course those defending BR will say that BR can't cover for all possibilities - which is true. But other companies are smart enough to include a second tether point in their strap system.
So whether BR is responsible or not, or whether it's a flawed system or not, the fact is, some users are reporting that the lens release button gets pressed. The smart and not so arrogant companies then try to mitigate that risk by including a small secondary attachment point. BR has their tether kit so they acknowledge that there is a risk, however small it is.
Since I spent so much money on my camera and lens, I decided to buy the Joby tether strap (i like looping the cord around the camera attachment point instead of forcing a ring through it like the BR kit (faster to loop), and I like that the joby has a locking carabiner - BR's tether kit does not appear to be locking ). I've never had my BR strap release accidentally, but for 10 bucks it's cheap insurance.
