Images of us can be sourced from any number of places: social media, government surveillance, private surveillance. Video less so but from the same sources. Audio from phone companies, VoIP services, surveillance, etc. Health data easily from a number of private companies if you use new-age "health" services, or less easily (illegally) from health records.
Maybe we can find solace in the fact that is or will soon be infeasible to avoid, so we needn't try to avoid it.

It's the meager solace of the absolution of personal responsibility - there's no way to avoid it, so at least no one can say "why did you allow that to happen to you".
Even decades ago I gave such reported concern with photographs more credence than the typical western account of it. I also wondered if the translation was precise enough -- could it (in some cases) have reflected a concern with "essence" more generally? Even without reference to a soul the concern can be a bit immaterial.
