AdSense is what it is, and it's not likely to change, because for every publisher that drops out, there are a ton more to take his or her place. And those 100 junk sites that replace you might end up making Google more money than you do; if their sites are really junk, people will be more anxious to leave them.
We're none of us as high in the ecosystem as we'd like to be, but that's the product that Google offers, and buried there in the terms of agreement they reserve the right to change the product (and make no guarantees as to the continuing success of the product) as a condition of signing up.
That's why my partner and I take the AdSense money and use it to fund other websites and marketing efforts, instead of trying to live off it.
