Except their LTS is a lie or maybe plausible deniability for businesses that DGAF. They have no idea what they are doing with backports and lack thereof. And if you aren't paying you aren't even receiving many of the updates.
Are you sure you didn't mean RedHat? Last I checked there's no requirement to pay anything in order to use an LTS release of Ubuntu. Even if you go with Pro to get those extra years of Extended Support (to make it ~12 years?) you still get up to 5 licenses for personal use. No money asked, no *BS* subscription model. Isn't that more than enough any non-commercial user?
