I'm just going to put out there that I don't think thats remotely what he's saying? It looks to me that his actual concern is that he could pay money to drive traffic to his comic, and that tapas would benefit from the ad rev of that traffic, while he neither gets the ad rev or views from it.
Whether or not this is happening is up for debate, and I think Tapas wants people to sign up, so I doubt there intention is for this to happens so they can greedily eat up all that ad revenue without splitting it.
I'm pretty sure his reference to family and friends signing up is just meant to say "I've been promoting this to people I care about, and I'll be mad if my hard work enriches tapas, but they do nothing to help me/creators like me succeed". I personally disagree that thats happening, but I think thats what he meant.
Pardon me if I'm wrong on any accounts @skicoak and @Croik
Edit: just adding that mostly I am otherwise in agreement with Croik, I just felt like this mischaracterized ski's point of view, and wanted to offer clarity just in case it was helpful. =P
