First of all, to the question itself, I would like to answer with a question that explains the confusion in which we find ourselves as citizens faced with this mechanism: who can answer this question?
Who can know if this data is used in a fair way? Who controls it? Are the bodies that have access to this data not using it for purposes other than those for which it was intended to be used in the context in question?
We don't know. There is an opacity that arises at some point, ultimately, and no citizen has the time to check that out.
So we are strictly bound by relationships of trust. Whether we trust these entities or not, in the first instance, we cannot verify that. Secondly, the question that arises here must be broader. I insist on this, ladies and gentlemen. The question cannot simply be about one tiny use, it must be about the mechanism and all its possible uses.
