As a former windows phone user and .NET developer who is currently a mobile developer, Microsoft definitely treated mobile developers worse than any other company.

They killed what small progress they’d made on their ecosystem 2 times, simply because they got bored and decided they didn’t like the technology stack they’d previously mandated and supported. They deserved to get buried in that space.

Meanwhile Apple have kept what is essentially the same technology stack for the past decade. Sure there’s been some pain, but almost all of it had some purpose that moved the development of apps forward.
