Apple Inc. and Amazon.com Inc. are removing Parler from their services, part of a growing backlash after the social media network was among those used to organize Wednesday’s riots at the Capitol.

Apple dropped Parler from its App Store, while Amazon’s cloud unit decided to stop hosting the social media company starting Sunday night. They joined Alphabet Inc.’s Google, which removed the app from its Google Play store on Friday, saying that it created an "ongoing and urgent public safety threat.”

Parler, which is popular with extremist groups seeking an alternative to more mainstream social media sites, has come under fire since the storming of the Capitol by a pro-Trump mob. The move by the tech companies will leave Parler ending the weekend without easy access to virtually all of the world’s smartphone users, and scrambling to find a new company to host its services.
