Salesforce.com Inc. said it would press regulators in the US and Europe to block Microsoft Corp.’s $26.2 billion acquisition of LinkedIn Corp. (NYSE: LNKD), arguing the deal would hurt competition by giving its business-software rival too much control over the social-networking company’s vast pool of data, The Wall Street Journal reports. Burke Norton, Salesforce’s chief legal officer, said owning LinkedIn would give Microsoft an unfair competitive advantage because it could block rivals’ access to the data on its membership. He said the deal also raises “data privacy issues” that Salesforce thinks US and European Union authorities should scrutinize. Salesforce’s public opposition to the deal comes three months after it lost a bidding war for LinkedIn to Microsoft.
