It clearly states that 5w-20 is fine to use now, but the note at the top of the TSB says to stick with what's listed in the service manuals, owner's manual and oil cap, which happens to be 5w-30.

Looks like the dealer drew his own conclusions about what's best, just like you did when you started using and recommending Yaris owners to use 0w-20 because of UOAs for non-Yaris motors, and because the TSB said 0w-20 was okay to use in a Corolla, Scion XD, etc...but if I can read between the lines I'm guessing that you drained out the 0w-20 and took the dealer's advice about the 5w-20.
