An obvious end-goal for car companies is turn all ownership into ten year leases, at the end you give the car back and they recycle it replace the battery and sell/dispose of it.
That implies they can avoid competitors doing something different. The hardest part about building an economical electric car has been cost-effectively producing the battery. Within a few years that will be a commodity.
Then what stops a new car company from forming that will sell you a car that lasts for 20+ years and you own it? Only the inability to get customers because the incumbents are offering a better deal. So to stop it they'd have to be offering a better deal.
