Chris Hill: Let's move on to social media. Last Thursday, an official-looking Twitter account for the pharmaceutical giant Eli Lilly tweeted out the following message: "We're excited to announce insulin is free now." This was not the official Eli Lilly account, it was fake. Reportedly it led to some amount of insider selling just reacting to the possibility that it was the official account. Friday morning, executives at Eli Lilly ordered an immediate stop to advertising on Twitter, and this is not a company we talk about very often. Just for those unfamiliar, this is a $330 billion global company with a massive advertising budget and Elon Musk would probably prefer that they stay advertising on Twitter.
