@jbhall56 the 70/30 split is justifiable since the owner is the actual creator of the product. If one broker can't make sufficient profit from selling your data, some other one will. Free market at its best.
Likewise, if you want to display ads on my computer, then you must pay me for the network bandwidth, memory, and CPU time consumed in delivering and displaying your ad on my systems. You've all been using my compute resources for free, that has to end.
