Takeaway: Tesla want more batteries.
Global sales in 2018 (of light passenger vehicles) were around 70M. Absent chip shortages and financial crashes, we could expect to hit 100M in three or four years.
Yep, Tesla wants more batteries. And this number, 70M, is why sticking with Nickel-Cobalt is a Bad Idea.
There's a lot more iron and phosphorus available for a lot cheaper; demand for Nickel and Cobalt will push their price... er, very high.
This becomes exponentially harder as they add more and more power hungry vehicles to their lineup (see Cybertruck / Semi) and market more Mega/Gigapacks to grid operators.
It makes sense for Tesla to try to get as many batteries as possible from as many sources as possible.
Before Musk bought Tesla, policy-makers in the US and Europe were all "electric vehicles are a nice idea, but simply impractical and unfeasible. So our vehicle manufacturers tell us".
In the short span of ten years, electric vehicles have become mandatory in many Western countries, starting sometime in the next 10 to 15 years, and they are headed that way in many more.
And that is down to Musk. Whatever his--many and grievous--personal faults may be, and whatever else he does short of mass murder, he deserves our gratitude for this alone.
That is exactly what has happened and was a success as a business was created that no longer relies on credits and it has clearly accelerated the advent of EVs.
Not sure what your issue is with that.
