It could be argued that Elon Musk is a public individual with public views. Arday was just a poxy lecturer, whom an avowed racist decided to go after. As an autistic person, Arday's sensibilities were likely extremely heightened by this badgering hack with 'questions', which to Arday could have felt exceedingly threatening to the core of his being. So much so, he attempted to appease matters - autistic persons are often people pleasers because they are aware they unwittingly make all kinds of faux pas, so are always conscious of the possibility of inadvertently breaching social mores - and adjusted the 300 miles in one month to 600, in an effort to mitigate the perceived terrible crime of exaggeration.
So yeah, getting Carter-Ruck onto TES - not the hack personally - might be OTT for a non-divergent person, but I can see Arday went into blind panic, and when the persecution continued killed himself in a fit of terror.
