Five technology companies, Rackspace and Indiegogo among them, took to Capitol Hill on Thursday to testify in front of the House Judiciary Committee about the importance of technology to innovation. The hearing, in front of the Subcommittee on Courts, Intellectual Property, and the Internet, followed one last week by a group of copyright holders and their industry organizations. Amid a sea of feel-good talk about the benefits of open source, Rackspace VP of Intellectual Property Van Lindberg made some really good points about the drawbacks of current copyright law.
