"Hardware support for Linux PCs is poor and lacks the manageable of Windows PCs with Active Directory and GPO, or JAMF for Macs. Enterprise software usually doesn't support Linux. Linux PCs are uncommon for personal use and corporations don't want to train users how to use Linux."
I would dispute the "hardware support" comment. Linux has pretty good hardware support nowadays. And "enterprise" software is a vague term here. For desktop Windows, of course Microsoft will have that covered every which way, but for things such as authentication, authorization and security, Linux has a place. A comment about adding "Redhat" to the mix is not talking about desktops (necessarily) but servers and security.
