If you had a support contract with Microsoft for your Windows installs and CrowdStrike is breaking your system they'll tell you to go talk to CrowdStrike, yes.
Ok I didn't realize that crowdstrike was more of competitor or maybe a hacky add-on (like a NOS). I was under the impression that it was something more in cooperation (not owned by or anything) but with Microsoft in terms of market support.
CrowdStrike absolutely is a competitor to Microsoft. Microsoft sells licensed software in the exact same market as CrowdStrike. Microsoft even sells Microsoft Defender for MacOS and Linux. They're direct competitors.
