...This isn't the first time this kind of thing has happened, either...

This is technically the 3rd time, with just Microsoft alone.

They turned off eBook authentication servers for "Microsoft Reader" (.LIT) format years ago... (2012?) Then, after they launched their also-now-dead store on Windows Phone which had some eBooks, well... that went away too...

Next - how many subscription/Music services has Microsoft launched and then abandoned? More than one, but I remember: PlaysForSure" - DRM servers turned off 11 years ago...

So - unless it is Xbox, don't think Microsoft is going to be a reliable source for your digital media.
