Activision Blizzard Games Must Appear on Competing Cloud Services

A tweet from Brad Smith outlines one of the consequences of the EU Commission approval of the proposed Microsoft/Activision Blizzard merger. Presumably, this hinges on the deal going through. The Microsoft vice chair and president explains that "popular" Activision Blizzard games must be automatically served through competing cloud services worldwide:
The European Commission has required Microsoft to license popular Activision Blizzard games automatically to competing cloud gaming services. This will apply globally and will empower millions of consumers worldwide to play these games on any device they choose.
