Social-media platform Parler has sued Amazon.com Inc. after the tech giant abruptly ended web-hosting services to the company, effectively halting its operation.

In a complaint filed Monday in Seattle federal court, Parler alleged that Amazon Web Services kicked the company off its cloud servers for political and anti-competitive reasons. The conservative social network founded in 2018 exploded in popularity among supporters of President Trump after the November U.S. election.

“AWS’s decision to effectively terminate Parler’s account is apparently motivated by political animus. It is also apparently designed to reduce competition in the microblogging services market to the benefit of Twitter , ” according to the complaint, which also accused Amazon of breaching a contract between the parties.

Amazon said Saturday that it would cut off Parler because it wasn’t confident in its ability to sufficiently police content on its platform that incites violence. The company said while it would no longer provide web services to Parler after Sunday at 11:59 p.m. Pacific time, it would preserve the platform’s data and help it migrate to different servers.

In its complaint, Parler also accused Amazon of applying a double standard than with other platforms, noting that Twitter had recently signed a multi-year web-hosting deal with the company.
