Does your company have a ton of thick-client apps? I feel like so many workloads are on the web right now and thick clients are slowly becoming a thing of the past - but maybe in Enterprise there are still stubborn thick client Win32 apps that are mission critical.
If I were starting a company today I would make sure that the majority of my apps were web based. (CRM[netsuite or sf.com], O365/GoogleDocs, workday|gusto, etc.)
Most high-security environments (banks, govt agencies etc) have a large on-prem footprint. Then there's specialised industries like manufacturing, science and engineering who typically have a bunch of embedded systems, often running ancient versions of Windows or something that needs to talk to a local ancient server. And many old companies have tons of legacy apps which are a PITA to migrate to newer infrastructure. So yeah, plenty of folks out there using omprem gear, it's kinda the reason why Broadcom is able to what it's doing - lots of suckers out there who're married yo vmware and can't get a divorce.
Reminds me of setting up VMware Workstation with USB ISA cards to keep a line running. Ugh
