Well the / is an Indicating Alternative by definition. So it's not my semantics that are off.

Indicating Alternative:
The forward slash can be used to separate or indicate alternatives, similar to the "or" connector. For example, "plaintiff or / and defendant" could mean either plaintiff or defendant, or both.

As in this could be one of the two or both, but does not include both.

and or &

him/her
he/she
they/them
etc....

There would be no need to say that you have access at transfer airports and not at arrival if it were a requirement for both airlines to be sky team members as you would be on a departing flight from a sky team member for both, but it defines that as well, and says not on arrival.

I understand the site you are referencing, but I am referencing Deta's site, and Delta sold me the Delta One ticket, connecting on a Business Class "J" Fare marketed by Delta but operated by ITA.

The real point is this is further confusion and Delta should clear it up. It also shouldn't be making look like I have access on the Delta App, if I don't, but it does.

I'm not on hear to argue about the petty semantics of it....but you brought it there. I originally posted this as a heads up to other flyers trying to help others out, and seek clarity on the recent changes with ITA and Delta, heck many didn't even know there were still benefits for Delta pax flying on ITA. Other issues remain such as ITA charging for seat assignments, when Delta's site says the only benefit that will be lost is the access to the ITA lounges.
