CMA is trying to stop a future where ABK content is locked behind a single/strong cloud gaming provider.
True.
Despite not knowing how cloud gaming will develop,
True to an extent, they want to preserve its future and not have it be pre-monopolized.
how important ABK content will be to cloud gaming
ABK content is important to everyone, they are the largest independent publisher for a reason.
what kind of cloud gaming models will emerge
Which is great for consumers, maybe someone comes up with a better service than xCloud, that service deserves to not be kneecapped by not having access to powerful content or having to pay through the nose for Azure/Windows licensing.
if ABK will even want their content on any cloud gaming services or which services.
Literally mentioned in the final report that ABK
does in fact retain interest in putting their content on cloud services. The only issue is them wanting to maximize terms in their favor.
Their decision based largely on uncertainty and assumptions does stop a hypothetical future where Microsoft in 10 years time restricts cloud gaming access to their service
It's not assumptions when Microsoft only went to 10 year deals because of regulators (in fact it was literally called out in the final CMA report), what they initially wanted was to lock up ABK asap. Also they have internal communications from ABK and MSFT that likely prove their point, they just have to redact it for plebs like you and me.
A lot of assumptions being made based on an uncertain future in the hopes that specific outcomes don't come to pass, outcomes that could be remedied with a remedy package, something the CMA doesn't want to do because it would require their involvement.
The gist of what they are saying is, "when it comes to Cloud gaming, you have shown that you won't behave unless I am always watching, and I don't want to expend the time and energy into watching you at all times", and it's pretty reasonable imo.
Microsoft rejected the idea of splitting off COD, so they get what they get.
The decision to block may also disincentive investment into this growing nascent market. All to stop a hypothetical future that doesn't have much if any evidence to support.
Literally the opposite, we are already seeing Amazon Luna trying to get into the UK market, and there will be more to follow, the market is still open for anyone who wants to get in without being enslaved to Microsoft's terms. Be it Sony, Apple, Meta, Nintendo etc.
