On Jan. 8, Apple sent a letter to Parler’s executives informing them about complaints that the app had been used to plan the storming of the U.S. Capitol Building by violent Trump supporters two days prior.
“We want to be clear that Parler is in fact responsible for all the user generated content present on your service and for ensuring that this content meets App Store requirements for the safety and protection of our users,” the letter read, according to The New York Times.
Apple warned that “to ensure there is no interruption of the availability of your app on the App Store,” Parler must submit an update as well as a “requested moderation improvement plan within 24 hours of the date of the message” (which was sent the morning of Jan. 8), per BuzzFeed News. If Parler did not comply, Apple would remove its app from the App Store.
On Jan. 9, Apple made good on its ultimatum and removed Parler from its app store.
