GovTechGuy writes "On Friday we discussed news that Texas Attorney General Greg Abbott opened a probe into whether Google ranks its search listings with an eye toward nicking the competition. Google suggested the concerns have a major sponsor: Microsoft. In question is whether the world's biggest search engine could be unfairly disadvantaging some companies by giving them a low ranking in free search listings and in paid ads that appear at the top of the page. That could make it tough for users to find those sites and might violate antitrust laws. Abbott's office asked for information about three companies who have publicly complained about Google, according to blog post by Don Harrison, the company's deputy general counsel. Harrison linked each of the companies to Microsoft."
