They mention there that made a deal to use Azure (instead of AWS or Google Cloud) to store the Sega AAA GaaS MP ("super games") game servers and gamedev repository servers.
Nothing there is related to including Sega games on GP or blocking Sony exclusives. It only says Sega will use Microsoft's cloud server technology.

The details themselves are in the latest leaked court documents. Don't have a link to those but it shouldn't be hard to find.
I may be wrong, but that quoted user seems to be a random annonimous internet user.
Sega focuses now more on multiplatform and supporting more the game subs (not only GP) because it's one of their main company goals of their current FY2022/3- FY2024/3 medium-term plan, not because a supposed (and fictional, as far as we know) deal with MS. Sega has been saying that way before signing that deal with MS to use Azure (not to get games in GP or to block PS exclusives).
Sega said this last year to their investors (and as I remember, the year before), quote from the "SegaSammy integrated / anual report 2022":
"We will expand touchpoints with users and
maximize earnings opportunities by reinforcing simultaneous worldwide releases and the multiplatform deployment of content.
We will also focus on remaking and remastering existing IPs and support subscription-based services to prolong product life cycles. Furthermore, we aim to strengthen user engagement and increase the value of our IPs through a mix of media and other approaches to connect these IPs with more people."

If in that 2022 document you search "multiplatform" you'll find many matches, there's one more regarding Atlus:
"from the year ending March 2023, working to further expand the global fan base by actively developing titles for heretofore unsupported platforms".
In the message from the CEO in that Integrated 2022 report (for the fiscal year that ended March 20222) he mentions again to focus more on multiplatform and game subscriptions as part of their goal.
And they also said that in the year before in their Sega Integrated (annual) report 2021:
"
Our initiatives will include expanding touch points with users such as by the multiplatform deployment of content and simultaneous worldwide release, prolonging product life cycles by remastering and remaking IPs and other measures, and strengthening user engagement through a mix of media. Over the long run, we aim to create “Super Games” that can bring in sales of ¥100.0 billion overtheir lifetimes"

This other image is from that 2021 annual report (talking about their April 2020-March 2021 year + plans for the future) too, the first part of that strategy is "stregthening global roll-out, multiplatform support, multilingual support":
You can search "multiplatform" or "subscription" in that 2021 document and you'll find many mentions again.
So no, if Sega had the new Virtua Fighter 5 on launch day on PlayStation Plus or some other game in GP, included many of their games on MS+Sony+Nintendo game subs and some of their formerly exclusive IPs now are multi is because this is part of the main goals of Sega's medium term strategy, something decided years before they signed a deal with MS to use cloud server management services (unrelated to blocking exclusives -as far as we know that doesn't exist- or include stuff in GP-that would be a separate deal and while Sega also includes games in Sony and Nintendo game subs-).
Well, it's not that I believe it based on nothing. I have someone that I trust to give me the thumbs up or down.
It's not worth having arguments about...we can just see how it shakes out in a few months or so.
Do you mean that you asked someone you trust to verify if Sega is making a Wipeout game and told you that it's happening? I'd be super happy if it's the case.
