I think some people will find an advantage in flagging untold numbers of research papers as frivolous or fraudulent with minimal effort, while putting the burden of re-proving the work on everyone else.

I'm curious about your statement that transdermal overdose is impossible. If I applied this to the entirety of my body simultaneously, how would my foot know to stop dragging in the potassium iodide after my neck got its fill?
The word lying implies that Reuters was aware, either before or after publication, that their information is untrue, and they published that false information purposely and failed to correct it.
On that basis, it doesn't seem like Reuters is lying. It seems like Reuters has been accused of lying, by someone with a history of misunderstandings with the truth.
It may be the case that they have lied. That would be a pretty egregious act by Reuters. It may also be the case that Elon Musk has reason or incentive to cast doubt on the story whether it is true or not.
Trust the process!
