Salesforce's (CRM) - Get Report decision to attack Microsoft's (MSFT) - Get Report deal to buy LinkedIn (LNKD) is not characteristic of the company and is quite puzzling, says TheStreet's Jim Cramer. The cloud computing company called on EU regulators to investigate whether Microsoft's $26 billion bid for LinkedIn violates antitrust laws. Microsoft is expected to seek EU antitrust approval in the next few weeks for its largest ever deal. Salesforce.com lost out in a bidding war for the social networking site in June. The San Francisco-based company added that it believes the acquisition raises "significant antitrust and data privacy issues" that should be fully investigated by antitrust authorities in the U.S. and EU.
