1. Somehow I feel this is because MS is trying to push dynamics CRM more 2. MS rarely sues over patent matters, usually they do cross licensing deals, so maybe they tried that here (as clear from Salesforce jan filing) and that didn't work out. I am sure Salesforce being quite a old player will have patents MS might be interested in using/licensing. 3. People criticizing the patents they are suing for, remember two latest case that MS lost, one of them for basically saving a word file in xml format. They lost millions and The judge actually ordered them to stop shipping Office till they fix it. Based on that as a shareholder I would want them to go out and make some money from their patent arsenal even if it involves suing.
