This is yet another blow for Twitter, which is trying to take
back its own narrative in an effort to boost its slumping stock
price. The company’s VP of Communications, Natalie Kerris, left
Twitter unexpectedly earlier this week, and at least two other
members of the company’s tiny communications team have left in
the past six weeks.
Prosser, in particular, had a lot of key responsibilities on the
team. As head of corporate comms, he handled press for most of
Twitter’s executive turnovers (and there have been plenty). That
meant he was also dealing with company earnings every quarter
(also a pretty tough assignment). As a result, Business Insider
named him the top tech PR person in 2015.
