Parler sued Amazon Web Services Inc. over supposed antitrust violations after the cloud hosting service suspended the social network.

The emergency lawsuit, filed Jan. 11 with a U.S. district court in Seattle, claimed that the Amazon.com Inc. unit's move would reduce competition among microblogging services, to the benefit of Twitter Inc.

Twitter permanently suspended the account of U.S. President Donald Trump, saying his posts risked inciting further violence after the deadly riots in Washington, D.C. Parler, which bills itself as the "world's premier free speech platform," continued to share Trump's posts.

"AWS's decision to effectively terminate Parler's account is apparently motivated by political animus," the complaint said.

Parler also accused Amazon Web Services of breach of contract for not providing a 30-day notice before terminating its service. It further claimed that Amazon Web Services is intentionally interfering with Parler's business.

Parler asked the court to issue a temporary restraining order preventing Amazon Web Services from shutting down its account. It is also seeking preliminary injunctive relief and damages.

The suspension from AWS went into effect on Jan. 10 at 11:59 p.m. PST.

While Parler CEO John Matze initially told users that the site might be unavailable for as long as a week because of the move, he later said the site "will likely be down for longer than expected." He explained that Amazon's decision to cease hosting the service, along with similar moves from other major tech companies, had caused most of Parler's other vendors to also drop support for the site.

AWS' trust and safety team reportedly told Parler that it is "troubled by the repeated violations" of Parler's rules on content moderation. AWS also said it "cannot provide services to a customer that is unable to effectively identify and remove content that encourages or incites violence against others."
