The rules are unnecessary regulation of the Internet and a power grab by the FCC of congressional authority, argued Sen. Kay Bailey Hutchison (R-Texas), a sponsor of the resolution. “The FCC has essentially granted itself power over all forms of communications, including the Internet,” Hutchison said Thursday on the Senate floor.Opponents of the bill argued the rules are needed to protect Internet users and startups against discriminatory practices by a shrinking group of broadband providers. “Net neutrality is the free speech issue of our time,” said Sen. Al Franken (D-Minn.), in debate earlier this week.Republican concerns that the rules would limit investment in the Internet seem unfounded, with 2011 shaping up to be the biggest year for technology initial public offerings in a decade, said Sen. John Kerry (D-Mass.). The Republican-controlled House of Representatives passed a similar measure to strike down the Net neutrality rules in April.This week, President Barack Obama promised to veto the resolution if it passed.Grant Gross covers technology and telecom policy in the U.S. government for the IDG News Service.
