Spotify lost $4 billion in market value this week after rock icon Neil Young called out the company for allowing comedian Joe Rogan to use its service to spread misinformation about the COVID vaccine on his popular podcast, “The Joe Rogan Experience.”

At the end of the day Friday, Jan. 28, shares of Spotify were down about 12% from where they closed last week, according to data from Nasdaq, against a broader index that was flat over the same period. The hashtags #DeleteSpotify and #CancelSpotify also gained traction on social media, with many websites offering step-by-step instructions for users to remove the app from their devices.

Spotify took down nearly all of Young’s music on Wednesday, Jan. 26, two days after the Rock & Roll Hall of Fame musician reportedly issued the streaming service an ultimatum via his management and record company: “They can have Rogan or Young. Not both.”
