AdamC,
I'll not try and defend MS, but the only reason I can think of for the shorter term of this LTSC release is that Windows 11 is here and they don't want to deal with a long term OS past the new 5 year period. Just my guess. They have committed to an LTSC for win11 and maybe that will have longer terms again (but probably not).
As far as using it incorrectly... This should be an option for anyone that has a license to Pro (or similar level). There are a bunch of business/professional use cases that don't require or desire a lot of the stuff put into Pro. The entire motion picture industry is one very clear example, a large number of those machines are truly walled off from the rest of the world to try and prevent movies leaking out into "the wild". Decades ago "The Hulk" leaked on the web without the special effects, this being one concrete example I can cite. Obviously having a person inside to sneaker net the contraband out is something that no OS can prevent, but with the number of "electronic break-ins" on the rise, having a true air gap is required. Netflix might specify this in their workflow document, if you are getting funding from Netflix, you need to conform to their workflow, from cameras to file handling practices. I think a web search will find those documents for anyone wanting to look, they definitely have a list of approved cameras.
These movie companies also don't need all the wiz bang consumer oriented stuff, they come in, get to work, and if they are lucky go home at the end of the day.
The Long Term channel should be available to "normal" users, might cut down on all the debloat script stuff floating around the web that you never know if you can really trust! If you can't code the script yourself, you have no way of knowing if it contains a "surprise".
