My guess is there is some communication going out to every "manager", even the M1, that says this is your priority.

For example, I know of an unrelated mandate Microsoft has for its management. Anything security team analysis flags in code that you or your team owns must be fixed or somehow acceptably mitigated within the deadline specified. It doesn't matter if it is Newton soft json being "vulnerable" and the entire system is only built for use by msft employees. If you let this deadline slip, you have to explain yourself and might lose your bonus.

Ok so the remediation for the Newton soft case is easy enough that it is worth doing but the point is I have a conspiracy theory that internally msft has such a memo (yes, beyond what is publicly disclosed) going to all managers saying they must adopt copilot, whatever copilot means.
