There's always been a push in the automotive industry to make parts in cars that the average person can't replace or repair easily. If anything, this makes more money for the automakers (like Tesla) because they can setup all kinds of service licenses and the like at their leisure. And if a particular product line gets too long in the tooth, then you just killed off any authorized servicing and parts. Now you got an instant customer if they keep thinking it's worth it. Especially if Tesla were to institute some sort of trade in program that would be cheap to finance but great for PR especially if it touts the recycling angle. Frankly, I'm surprised no one would think such a possible outcome was going to happen. Elon's not dumb, he's a businessman first and foremost. Telsa cars aren't a charity. You buy them to feel good, they are nice fun cars to drive, then when the time comes you're likely to get bored with it anyways and want to trade for the newest model because you're a good little consumer, right?
