You don't. You either run your own stuff or you get paid by CPC/CPM or for ad space.
Unfortunately the average affiliate is dumb and apathetic. I can say this because I'm an affiliate too. But the point is nothing will ever be done because affiliates will never force the issue. They will just pick their noses and bullshit each other online about how they are rich and things are better than ever. Sponsors don't care. If the tracking fucks up and takes 40% of sales from affiliates then that just means 40% more for them without having to pay affiliates. Tracking has been getting worse with each passing year. At the very least honest programs would be upping the payout or the revshare percentage slightly to compensate but do you see this happening?
So the answer is to not be an affiliate if the terms for being one are no longer appealing.
