I find that the spoilers are often addressed within the first couple minutes of the episode so I'm not to concerned with it either way. Not to say that it will be unimportant, but it usually doesn't hold a cloud over the entire episode. (For example,in a recent episode the spoilers we had about frieza offering to join U11 were true but Dyspo spent about 2 seconds considering frieza's request and then it was over).
And with the power scaling of this series I truly have no idea if 17 or frieza are a match for Toppo
