@cratermoon @lunch yes, because monopoly power is bad, and abusing monopoly in one area (operating systems) to have a competitive edge over competition in another area (antivirus / EDR software) is also bad.
So in 2009 MS signed an agreement with the EU that they won't do that anymore, and allow independent AV / EDR vendors same access to Windows OS as Windows Defender enjoys.
It's not about pushing back. It's about Microsoft trying to leverage CrowdStrike to undermine anti-monopoly process.
