Microsoft has claimed that Sony pays developers for “blocking rights” in return for them agreeing not to put their content on its Xbox Game Pass subscription service.

As part of a document sent to Brazil’s Administrative Council for Economic Defense (CADE) to justify its proposed acquisition ofActivision Blizzard, theXboxfirm claimed thatSonyactively attempts to “inhibit growth” of Game Pass by trying to prevent content appearing on it.

The comments are part ofMicrosoft’s response to Sony’s claimsto the Brazilian body – which makes much of its responses public – thatXbox acquiring Call of Duty would be anti-competitive.

“Considering that exclusivity strategies have been at the core of Sony’s strategy to strengthen its presence in the games industry, and that Sony is a leader in the distribution of digital games, Sony’s concern with possible exclusivity ofActivision‘s content is incoherent, to say the least,”Microsoftclaims in the documents published by CADE.

Microsoft claims it ‘simply wouldn’t be profitable’ to make Call of Duty Xbox exclusive

“It only reveals, once again, a fear about an innovative business model that offers high-quality content at low costs to gamers, threatening a leadership that has been forged from a device-centric and exclusivity-focused strategy over the years.”

It then claims: “Indeed, Microsoft’s ability to continue expanding Game Pass has been obstructed by Sony’s desire to inhibit such growth. Sony pays for ‘blocking rights’ to prevent developers from adding content to Game Pass and other competing subscription services.”

The remainder of its response, and two further claims under the same section, are redacted in the document, presumably for confidentiality purposes.

Elsewhere in the document, Microsoft claimed that Sony “does not want attractive subscription services to threaten its dominance in the digital distribution market for console games,” arguing: “In other words, Sony rails against the introduction of new monetization models capable of challenging its business model.”
