Unity being a game engine, it's nice that other developers will be able to use the platform this way and not only Unity as a company, don't really understand the debate in the above comments as the company in itself isn't really the target, "Unity creators" are.
If you can run xCloud, you'll probably be able to run this too, never had any problem with Azure servers in gaming and much less at work.
I have no issues in Microsoft Flight Simulator nor Minecraft Realms and from what I understand it runs on Azure, I don't get why people get so upset about online only, the processing gets outsourced, how sweet is that ?
Portability of a game engine on many different providers is a good thing, it makes game creators able to pick the architecture they need from different platforms, imagine if it was only AWS running it all, no price range, just a monopoly, small time creators might not be able to afford it, certain commercial bias can happen between big tech companies, etc.
A news welcomed by those with a dev kit for sure
