By Marina Lopes NEW YORK (Reuters) – International Business Machines Corp has not relinquished its customers data to the U.S. government and would challenge any orders to do so, the company said in a blog post on Friday. The post by the worlds largest technology service provider is the latest backlash by a tech company against U.S. electronic surveillance practices, after published reports on Wednesday that alleged the government used websites to break into computers. IBM has not provided client data to the NSA or any other government agency under any surveillance program involving the bulk collection of content or metadata, Robert Weber, IBMs senior vice president of legal and regulatory affairs, wrote in the blog post. If the U.S. government were to serve a national security order on IBM to obtain data from an enterprise client and impose a gag order that prohibits IBM from notifying that client, IBM will take appropriate steps to challenge the gag order through judicial action or other means, Weber said.
