The nonprofit Internet company Mozilla came out against CISPA late Tuesday in , saying: "While we wholeheartedly support a more secure Internet, CISPA has a broad and alarming reach that goes far beyond Internet security. The bill infringes on our privacy, includes vague definitions of cyber security, and grants immunities to companies and government that are too broad around information misuse."

For those keeping score, Mozilla's stance was countered by software giant Microsoft quashing reports that it had withdrawn its support for the bill. last week that Microsoft had issued a statement saying it would support the law only if it would allow it, "to honor the privacy and security promises we make to our customers."

While CNET's Declan McCullagh stressed that this was "not a complete reversal" from Microsoft's position when the legislation was introduced in November 2011, numerous others took it that way.

Over the weekend, that, "CISPA has just lost a powerful backer, with Microsoft withdrawing its support for the controversial cybersecurity bill ..."

But Microsoft responded in a statement , saying, "Microsoft's position remains unchanged. We supported the work done to pass cyber security bills last week in the House of Representatives and look forward to continuing to work with all stakeholders as the Senate takes up cybersecurity legislation."
