Or... We could change the law to make it clear that when you buy some hardware you do own it, and to punish businesses that attempt to abuse their customers with owner-hostile retrospective software changes (to hardware products or otherwise). Consumer rights laws exist, and they can be strengthened if necessary to ensure fairness in the market.
>> We could change the law I think the law will only change for worse. It all starts with the DRM/DMCA.
However, some parts of the world are more enlightened when it comes to consumer rights. For example, the EU has at least attempted to make constructive regulatory interventions in the interests of consumers as technologies have evolved, even if their success has been mixed. Here in the UK, aside from EU rules we're inheriting after Brexit, we too have some solid basic consumer rights laws of our own. The EU+UK market is already larger than the US one, so that's a pretty big incentive for Tesla not to try those sorts of games around these parts. And if we get reasonable treatment, maybe that's enough for customers in places like the US to demand the same standards.
