This is.. not huge news? Google is discontinuing its own Widevine server, but Widevine is not going anywhere, you can still run your own server or use any of a number of third-party hosts offering it:

And surprise surprise, the blog post in question appears to be very thinly disguised marketing for one of those third parties.

Also, the Google service was free and came with no SLA or support, meaning anybody remotely serious about DRM was not relying it on in the first place.
