If Tesla's business model bothers you don't buy one and don't invest in them either. Folks buying Tesla's do so knowing what they are getting and are happy with it. I'd love a Tesla warts and all but for the cost.
Then don't buy one.....Sure OTA update can be nice. On the other hand I think it can be an excuse for releasing stuff before it's ready. Potential for a big problem. I'm not that keen on driving around a car with hardware that doesn't work yet because he software isn't ready.
