i this you linked to the wrong unity8 ... unityx seams to be something different ... https://lomiri.com/ is the renamed unity8 that is used in the ubuntu touch phones now ubports phones
I did not link to Unity8 at all in my article.
The article is about Rudra Saraswat, so I linked to Rudra's project, UnityX. As far as I know, he isn't working on Ubuntu Touch at all.
