"I agree, that the EUC growth spurt of 2020 and 2021 can't be repeated. Maybe there's a way to squeeze more revenue from the installed base, but that seems like a 'no-win' situation if raising prices drives away some of the customers."
Not repeated or replicated with the traditional VDI / application virtualization approach. Customers are looking hard at and actively moving to Zero Trust frameworks, which means they're also investing in stuff like application modernization, SaaS, and SASE. No longer do you need an expensive VDI infrastructure and associated licensing just to get to corporate applications and resources. Those who still have a valid use case for VDI can increasingly move those seats to Microsoft for AVD, or perhaps to one of the upstart DaaS competitors which are easier to consume and manage.
