Can Yasuo - Unforgiven move a teammate's unit in 2v2, including from their base to the battlefield?

Ruling: Yes, Yasuo - Unforgiven can move a teammate's unit because "friendly" includes your teammate. The card has errata that specifies when moving a teammate's unit to a base, it goes to the owner's base, and the errata also covers moving units from a teammate's base to the battlefield.

Nuances:

• When moving a teammate's unit to a base, it must go to that unit's owner's base (not Yasuo's owner's base)
• The errata specifically addresses both directions of movement involving teammate units
