Not saying I agree that being closed source is in the public good, although one could certainly argue that accelerating the efforts of bad actors to catch up would not be a positive.
Tell about a technology you think but dangerous, and I'll give you fifty way to kill someone with it.
Plastic bag for example, are not only potentially dangerous, they make a significant contribution to the current mass extinction of biodiversity.
That is news to me, how exactly do they significantly contribute?
This was the most concrete, so some contribution (no news to me), but not in a significant way, like pesticides do, for example.
"When turtles eat plastic, it can block their intestinal system (their guts). Therefore, they can no longer eat properly, which can kill them. The plastics in their tummy may also leak chemicals into the turtle. We don’t know whether this causes long term problems for the turtle, but it’s probably not good for them."

Now, this was really an incidental point, not the nub of the comment, and since this is really not the topic here, I don't mean to deeply develop it here.
