Beyond security, the "Diagbox 7.57 VMware" phenomenon highlights a friction between consumers and manufacturers.

The complexity of maintaining this setup—managing USB pass-through, configuring virtual network adapters to block internet access (to prevent the software from "phoning home" and deactivating)—demonstrates a high level of technical proficiency among independent mechanics. Yet, it also signifies a failure on the part of the manufacturer to support the longevity of their vehicles in the independent repair market.
