Ubisoft Opting out of Disc to Digital is Very Disappointing (But Not Surprising)

I have around 50-60 discs from the Xbox One and Xbox Series era, and of all of them only 6 did not give a license. 4 of them were Ubisoft titles (the others were Forza Horizon 4 and Marvel's Guardians of the Galaxy, I presume this is due to licensing).

Far Cry 4, Far Cry 5, Immortals Fenyx Rising and Watch Dogs Legion all failed as "not participating in digital licensing".

I don't know if this is because of Ubisoft +, their general incompetence this past decade or a combination of the both, but I was surprised such a large publisher hasn't gotten involved with this scheme.

I've heard Square Enix has the same issue, but all my titles from them were digital anyway.
