LTSC is considered by some folks to be "debloated" because it doesn't add consumer apps, and doesn't take Feature updates over its lifetime. In fact, it doesn't come with MS Store unless you manually install the pre-requisite packages.
LTSC is built on Enterprise, which is really the same as Pro or EDU but with different GPO policies built-in. But legitimate LTSC users are paying more for their licenses and support contract than you are. So MS has to convince the retail users to use their online services.
