If they detected a change A in cloud 1 correlative to a change B in cloud 2, then information is being transmitted instantaneously. The question then is whether it must be simply random, or whether a change/measurement in cloud One can be induced that is consistent with another change/measurement in cloud 2. Plus a clock and filters for noise, etc.
“then information is being transmitted instantaneously”
Yes, but not useable information. Until you can distinguish whether it is purposefully transmitted information or random noise, it is unusable. And to distinguish that requires classical (sublight) communication of information.
Believe me, you’re far from the first person to think it can be used like this, and far from the first to be disappointed that it cannot. This has been well established for decades.
