My privacy should not depend on your disinterest to abuse my data. There were many cases where workers abused access to sensitive information like tracking data, and people that illegitmately access data don't always do a ROI calculation to see if it's economical to do so, often they do it e.g. for revenge or personal interests. Also, I think Apple did not stop this practice because it is in general unethical or illegal to collect and analyze such data (it is not), but because they are marketing themselves as champions of user privacy, and crowdsourcing speech-to-text translation of potentially sensitive user data without properly informing their users just does not correspond to that image. In addition, they might be afraid of facing regulatory action in the EU, which could greatly damage their image as well, so it's a reasonable decision to halt all data processing until they can ensure full compliance.
