This is Microsoft's problem with just about everything they've done consumer-side. Windows 10 Mobile is still a fantastic platform that was well ahead of it's time (Android Q is rumored to add both dark mode and a desktop UI, which W10M has had for years), and was killed just big selling points like Continuum were ramping up. And Universal Windows Platform has been harshly deprioritized in favor of Electron despite the fact that we're still a year from Windows 7 (the primary compelling reason to use Electron over UWP for a PC app) going away. Edge's rendering engine performs better than Chrome, but just as it's starting to reach basic feature parity and stability, Microsoft is axing it in favor of switching to Chromium.

Microsoft also seemed to be leading the foldable device trend both with the Courier several years ago, and more recently, the Surface Andromeda, but then inexplicably decided to kill them both and wait for their competitors to beat them to it. I have a Windows phone that runs Android apps as well as Android does but Microsoft decided to scrap the feature. Watching Microsoft both come up with the best solution to a problem and then brutally murder it before anyone can use it is probably the most painful thing to watch in tech.
