You see, Microsoft is in a very different place than it was when it first sued Motorola in 2010. Back then, the company under Steve Ballmer was bent on containing Android's growth wherever possible and giving Windows Phone a shot at recreating Windows' desktop monopoly. Flash forward to current CEO Satya Nadella and it's a different story. He's less interested in operating system dominance (in part because that's no longer realistic) and more in putting Microsoft's apps and services in front of as many people as possible,
even if that means supporting Android ahead of Windows. We'd add that Google isn't facing nearly as many threats as it has in the past -- there's less incentive to countersue and push for settlements. In either case, the hot-blooded competition that fueled the lawsuits has long since cooled down.
