Cloud based hosting service provider Rackspace has joined the ever expanding list of companies that are opposed to the US Stop Online Piracy Act (SOPA).

In a blog post, Rackspace CEO Lanham Napier, said that the controversial bill, which will get its final vote before the House Judiciary Committee, will do more harm than good, punishing innocent users in the process.

"The SOPA bill, as it stands, is a deeply flawed piece of legislation. It is bad for anyone who uses the Internet, including Rackspace, the more than 160,000 business customers that we serve, and the tens of millions of retail customers that they serve. It is bad for job creation and innovation," Napier wrote, echoing what other internet companies and free speech supporters have been saying for weeks.

He said that the bill will require the internet to censor their customers in such a way that it would go against the Digital Millennium Copyright Act.

Rackspace said that it had studied the bill in its current form and had concluded that it would fail to achieve its purpose and harm the economy, because IP thieves will continue to break copyright laws at the expense of innocent users.
