为了纪念自杀身亡的Aaron Swartz,ArchiveTeam发布了Aaron Swartz Memorial JSTOR Liberator,
这是一个基于JavaScript的书签工具,目的是让互联网用户“解救”已属于公有领域的JSTOR论文。
用户在浏览器上运行工具访问JSTOR它就会在上面下载一篇公有领域论文然后上传到ArchiveTeam,以此抗议JSTOR的限制政策。
STOR的服务条款禁止使用聚合软件下载和传播论文,ArchiveTeam的开发者认为,JSTOR没有权力对公有论文施加额外的限制。在Swartz去世之后,美国司法部宣布放弃针对他的指控,电子前哨基金会则呼吁修改过于严厉的计算机犯罪法律。
