Another point seems to be upgrade fees - e.g. with Volvo I have to pay for the dealers diagnostics software subscription, for the actual software update itself (yes, really), and for the time it takes because it blocks a slot in the dealers garage (and the diagnostics system). Upgrades effectively easily cost 700 Euro per year, and they can't even tell me what's actually changed (at least it's optional).

If we only had the technology to roll out tamperproof updates, even if it was via a USB stick... /s (At least the map updates happen exactly that way).

Ergo, I'm under the impression they're really just only using this to siphon more money from the customers.
