It is, but this isn't. The DMCA doesn't mention Trademark. That's a separate section of law because copyright and trademark are different things.
Crowdstrike submitting a DMCA takedown for alleged Trademark infringement isn't how it's supposed to work at all. Likely because they know this isn't actually a Trademark infringement case.
Cloudflare's automated system not being smart enough to see that is fine. Their abuse/counterclaim process being broken isn't. ( Not that that's new or unique )
Technique yes, technology I would question.
