Billed as the largest online protest in history, there is a local spin to the SOPA Strike, aimed at keeping the heat on controversial legislation aimed at curbing online piracy. Critics say the legislation is too broadly written, as to allow limitation of any social web tool that allows the sharing of intellectual property — think Youtube, Twitter and Facebook.

Today, a call for a ‘blackout’ has led to major websites like Google and Wikipedia to limit their functionality or site look to convey what could be lost if the federal legislation moves forward. Several Philadelphia companies have joined the fray, the day of a House Judiciary Committee hearing on the bill, even though President Obama has said he would veto the bill in its current form.
