I've never worked for Microsoft so I'm speculating, but I doubt their org structure supports that. The Windows team isn't going to be the same as the EDR team.

The EDR team might have more info about Windows internals than CrowdStrike does, but then again, maybe not; CrowdStrike already has to work pretty closely with Microsoft to get into the kernel in the first place, and Microsoft is (sometimes) pretty careful about 'bundling' antitrust concerns.

I think the feeling is that Microsoft as the company that has to field the blame for any problems in Windows has more incentive structures in place internally to "never further tarnish the Windows brand". CrowdStrike doesn't care if people blame Windows (and partially benefited in some parts of this news cycle from people blaming Windows for being the messenger), but Microsoft has nothing but skin in that game, and even if the team was in a terribly remote part of the org structure from the Windows team would still be incentivized to avoid making Windows (any more) the bad brand even if for no other reason than "shareholder value" and the equity stakes in their total compensation. (But Microsoft will have other internal incentives in place, especially the closer the team gets to Windows.)
