Twitter’s board of directors gathered this week to sign what sounds like a suicide pact. It unanimously voted to swallow a “poison pill” to tank the value of the social media giant’s shares rather than allow billionaire Elon Musk to buy the company.

The move is one way to fend off hostile takeovers, but what is different in this case is the added source of the hostility: Twitter and many liberals are apoplectic over Musk’s call for free speech protections on the site.
