It doesn’t matter. Distillation is impossible to stop. They could release an extension that intercepts requests and in return gives you a discount like Honey and get the same data.
Measures to stop "distillation", rate limiting, ID verification, etc. If there were such a method that didn't harm legitimate use it would already be in place (and some things are, but they don't really work, hence the OP).
Lots of things are impossible or very difficult to stop completely but measures can be taken to reduce their prevalence.
