This happened after Valve discovered that Ubisoft was marketing a cheaper $15 “starter pack” exclusively through its own Uplay store. The report suggests Ubisoft was effectively given a short deadline to fix the situation or risk losing its Steam presence entirely.

Another example cited in the same report involves Warner Bros. Interactive Entertainment. In 2017, Valve employee Kassidy Gerber reportedly informed Warner Bros. that preorders for Middle-earth: Shadow of War had been removed from Steam. The reason given was that the Steam price was “significantly higher than what was available at other retailers for the same version of the game.” According to the report, Warner Bros. leadership quickly reached out to resolve the issue.

Valve is threatening to delist games for undercutting Steam in price.

That is the allegation.
