How is this the app developer's fault? There's plenty of Linux, macOS, and Windows software that only runs on recent kernels because they use new APIs. Why would ANY developer target OSs that the overwhelming majority of their users don't actually use, skipping out on supporting modern functionality?

Edit: Really eager to hear from the folks downvoting about their great experiences bending over backwards to support SDKs from 2013 to target devices that literally can't even connect to a mobile network anymore.
