It's a sad day for the internet, and for freedom. The Cyber Intelligence Sharing and Protection Act, better known as CISPA, has passed the House of Representatives and is now awaiting a vote from the Senate. For those unfamiliar with what this bill allows the government and ISPs to do, it allows for companies and the government to legally share private information with each other in the name of cyber security. You can read more on it here. Luckily the Obama administration threatened a veto if amendments aren't made to reduce the privacy violations. You can read more about the bill's passage here.
So what can be done to stop this? Contact your Senators telling them to vote against the bill, if that's what you think should be done, and even write the president telling him to veto it if the bill passes the Senate. There are numerous petitions against this bill floating around, so do a quick Google search and sign.
