Eh, maybe. First for existing content it makes no difference, the creator already got paid to read the ad so whether you skip it or not doesn’t change the money that’s already in their account. The argument would be if people are regularly skipping the sponsored ads then companies might stop offering sponsorships. Considering this is currently limited to premium customers which a) tend to be the minority, b) still need to manually trigger a fast forward to skip the ad, and c) would likely fast forward through it anyway because they’ve already shown they’re willing to pay money to avoid ads, I don’t think this will actually make much difference. Worst case scenario it drives down the amount being offered for sponsorships a little.
