It seems there is enough pushback from Microsoft's enterprise clients because the W10 LTSC versions lack all the adware and most of the spyware that is pushed on the regular versions. Of course, they are not advertised anywhere and buying licenses through regular channels is impossible for a home user or a small company.
I haven't compared resource usage between my previous W10 Pro VM and my current W10 LTSC VM but it seems to start up much faster, and of course the aggravation from using it is way lower.
Ironically, my employer just replaces all of Microsoft's crap with its own crap, pushed out to every client through GPOs and SCCM and other tools. So we get full screen banners, sometimes by launching PowerPoint and showing a slide, about things like cybersecurity awareness or [minority group] History Month. And it takes many minutes to boot up and login and get a functional desktop with all that, plus the scanning by McAfee and Nessus and Tanium.
