Tech under attack after Parler goes dark, Twitter drops

Tech firms tried to contain a mounting backlash against their social media sites, with shares of Twitter Inc. and Facebook Inc. falling in early trading and rival platform Parler forced offline by Amazon.com Inc.

Twitter fell 7.8% in pre-market trading in New York after it banned President Donald Trump permanently for risking incitement to violence, citing posts referring to riots in the U.S. capital last week, removing one of Twitter’s biggest accounts. Facebook’s shares were down 2%.

Free-speech-centric network Parler, led by Chief Executive Officer John Matze, was taken offline early on Monday after Amazon Web Services shut down access to its servers, leaving it without an online home. Both Google and Apple Inc. kicked Parler from their stores, making it almost impossible to download the app.
