That doesn't strike me as a tradeoff based on a realistic assessment of the likely outcomes. For example, VW issued updates for the 2012 GTI only until 2018. Meanwhile, even if Google or Apple were to stop operating their maps services, you could switch from one to the other, or you could switch to OSM or whoever steps in.

In a way this is a blessing in disguise, because the moment a large car company thinks they can do software well, they'll want that team to be a profit center not a cost center, which means they'll start charging for subscriptions.

There's an argument that we're at Peak Mediocrity for car systems that one can own (at least at the levels that we think we own our cars now).

That makes it much harder to collect all sorts of useful statistics about the cars use, which is profitable, which is why all the manufacturers will eventually go with OTA.
