Microsoft have plenty of platforms and products that were abandoned overnight. It’s hard for me to even think of Windows Phone, for example, without thinking of what happened to WP7 buyers when they abruptly pivoted their mobile OS/runtime strategy with the incompatible WP8. The most they got was a WP7.8 update that skinned the immediately-dead platform to look like the new one.

It’s a matter of visibility and what kind of customers own the products being shut down. From a PR perspective there’s a big difference between killing an enterprise product with few large customers, and killing a consumer product with many small ones. Even if the few complaints are louder, the many complaints around the latter would still totally drown it out. I’m sure they have analytics to know how many people still use Windows Phones and weighing the possibility of an outcry e.g. if all their unsupported phones got 0wned and they collectively took to Twitter about it.
