I think this is semantics. You don't have to be a patent troll-an entity like you describe with no other real business, in order to go patent trolling.

MS is trying to be a troll under the bridge for Salesforce, and if you look at the patents, they are so broad and non-innovative that using them in an offensive manner constitutes trolling.

I don't think you can evaluate this by looking at the patents. If your sole business is patent suits, you're going to sue every time. If your business has paying customers, there's a chance you're going to spend more of your attention on them than your patent portfolio.
