If we look in the past we also have snake oil which is said to be a major cause for mistrust for doctors and medicine. Government had to step in and issue regulations in order for the public to regain trust and vaccinations is one of the very few remaining trust issues between the public and medicine.

If we want people to regain trust in auto-update there need to be something that prevent abuse. If that is regulations, liability laws, or just industry practice will be up to the future to decide. Until then a person will have to rational decide on auto-update as past people did with the uncertainty of not know what is snake oil and what is real.
