Apple isn’t providing security guarantees nor did it ever imply. It’s like Apple performed trust checks, and validated the developer.“Trusted Software” is an interesting term. I’m not sure why I should trust Apple on this. Lately, not only security but also economic and increasingly political reasons have been relevant for Apple when notarizing an App, hence giving it the “Trusted Software” label. “Trusted” for Apple does not necessarily mean it is in the customer's best interest.
