Interesting. What are the Audi and Target sponsored things you mentioned? Comics?
As for them being or not being canon, I'll keep them on the timeline since they don't conflict with anything else, and inspired by or not at least "fit" into the universe. Mainly, though, in terms of canon and not, I've found such things are very fluid and change depending on who you ask, officially speaking (like in this case from Marvel employees who apparently are involved with continuity on some level for the MCU) or not (fans like me).
Unless it conflicts with the established canon stuff, I'll leave it, or until Marvel publishes an official list of what's canon and not in the MCU, and again Marvel may ONLY consider the films canon.
