From The Washington Free Beacon:

Brandon Combs, president of the Firearms Policy Coalition, told the Free Beacon that links to CodeIsFreeSpeech.com have been blocked by Facebook, and Amazon has taken the site down from its servers. The website, which has republished the gun-design files at the center of the Wilson case, is a joint project of the Firearms Policy Coalition, Firearms Policy Foundation, Calguns Foundation, and California Association of Federal Firearms Licenses. Combs said publishing the files was within their First Amendment rights and the actions taken by employees at the tech giants is an attempt to censor them that he believes may have wide-ranging consequences
