[deleted] Nope, it appears as if they are just simply using a root detection library (called RootBeer).
I haven't seen anything suspicious else, so if any Swiss person is willing to try out the patch before I submit it to the official ReVanced patches repo send me a message either here (is that possible?) or to 1fexd [at] 420blaze.it
By the way, my Github is 1fexd, just to give myself some "credibility"
