Claim: Text circulating on Twitter (currently at 239.5K views) asserts that "Sony has signed deals with third-party developers to stop them from working with Microsoft."

Is Final Fantasy 16 coming to PC, Xbox and Switch?, Franey writes:
The document in question is Microsoft's Response to the CMA's 'Issues Statement' of October 14, 2022. Distinctly, the following paragraph:
Source number 240 directs the reader to a piece written by Engadget's Jessica Conditt published on October 19, 2022 titled
A 'Silent Hill 2' remake is coming from Bloober Team and it's a PS5 console exclusive. Conditt says "the [Silent Hill 2] remake will be exclusive to PS5 and PC for 12 months after release".
Of crucial importance, no evidence is furnished by Microsoft to support their claim that Sony has "entered into arrangements with third-party publishers which require the 'exclusion' of Xbox from the set of platforms these publishers can distribute their games on."
Indeed, the examples provided by Microsoft disprove their own assertion. Sony funded title Bloodborne, developed by From Software with assistance by Japan Studio, did not prevent From Software from working with and releasing other non Sony funded games on the Xbox platform. Similarly, while PS5 and PC are the only confirmed platforms for Final Fantasy XVI, there is no deal with Square Enix that prevents them from distributing other titles on the Xbox platform (see Chrono Cross, Star Ocean, and other recent Final Fantasy releases.)
Truth: The claim is unsupported by the very Microsoft document GamesRadar uncritically duplicate in their answer. Microsoft appear to mischaracterize individual exclusive deals—
a practice they themselves engage in—to mislead the CMA into delivering an decision favourable to their interests.
Side note: Even though Microsoft's assertion is almost half a year old, it's curious how the claim has gone viral on the eve of the CMA's decision whether to allow or decline Microsoft's merger of Activision-Blizzard. A skeptical mind might conclude the timing is conducive to "serves Sony right" type responses immediately following the verdict.
