Any Fortune 100 company go all in on Microsoft E5 Security Suite?

I am really curious if any large organizations have gone all in on the Defenders/Purview or have tried and ran for the hills. Mainly Defender for Endpoint and Defender for Office 365. Really all the Microsoft Defender products feel half baked.

Also is it just my company or has Microsoft been entrapping companies into getting E5 for the same cost as E3?
