really? 
you think that adding 15 KWH worth of batteries did not cost the company that much money? What exactly do you base that on? 
And I have seen you back the likes of koch bros and even backing the epipen which was charging $500 for something that was just $50 the year prior (and with ZERO changes). 

The profit margin on the 60 kwh with the 75 kwh drops into the single digits. Tesla counts on the fact that the owner will later on pay for the upgrade (and most do), which restores the profit margins to being similar to the market's profit margins. 

Immoral? Musk has to be the only moral CEO since bob crandel stepped down from AA.
