I think it has something to do with the fact that Microsoft had just invested close to $10M in Heroku in the weeks prior to the acquisition (making Microsoft the biggest investee in Heroku). Right now, Salesforce is positioning themselves against the Microsofts and the Oracles (versus the smaller CRMs like ZoHo, Sugar, etc.); the Heroku purchase was probably more strategic than anything else.

I think this is one of the reasons why Salesforce has agreed to let Heroku "run themselves" instead of taking over and ruining the party. It's also a good sign for Heroku customers since it's unlikely that Salesforce will make a ton of changes to Heroku's service until they can figure out how best to integrate the two services.
