REUTERS - Jan 11 - Apple Inc and Amazon.com Inc have suspended Parler from their respective App Store and web hosting service, saying the social networking service popular with many right-leaning social media users has not taken adequate measures to prevent the spread of posts inciting violence. The action follows a similar move by Google on Friday. Parler is favored by many supporters of Donald Trump, who was permanently suspended from Twitter and it is seen as a haven for people expelled from Twitter. Amazon's move effectively takes the site offline unless it can find a new company to host its services. Amazon suspended Parler from its Amazon Web Services (AWS) unit, for violating AWS's terms of services by failing to effectively deal with a steady increase in violent content.
