Jon Brodkin reports in ars Technica,

YouTube is a private forum and therefore not subject to free-speech requirements under the First Amendment, a US appeals court ruled today. "Despite YouTube's ubiquity and its role as a public-facing platform, it remains a private forum, not a public forum subject to judicial scrutiny under the First Amendment," the court said.

PragerU, a conservative media company, sued YouTube in October 2017, claiming the Google-owned video site "unlawfully censor[ed] its educational videos and discriminat[ed] against its right to freedom of speech."

PragerU said YouTube reduced its viewership and revenue with "arbitrary and capricious use of 'restricted mode' and 'demonetization' viewer restriction filters." PragerU claimed it was targeted by YouTube because of its "political identity and viewpoint as a non-profit that espouses conservative views on current and historical events."

But a US District Court judge dismissed PragerU's lawsuit against Google and YouTube, and a three-judge panel at the US Court of Appeals for the 9th Circuit upheld that dismissal in a unanimous ruling today.

...PragerU claims YouTube is a "public forum" because YouTube invites the public to use the site to engage in freedom of expression and because YouTube representatives called the site a "public forum" for free speech in testimony before Congress.
