I think you’re overestimating the importance of a TMS.
If I am, then so is Tesla. Do you have that much insight into battery longevity, that you know what Tesla does not ?
Battery chemistries are not all the same. Some need and can thrive at higher temperatures, some need and can thrive at lower temperatures.
For a commuter car, a wide temperature range battery that doesn't need a TMS would be the cheapest, lowest maintainance and most reliable solution. The Leaf with the 24kWh "lizard battery" is fairly close to this, with great results in cool places and OK results in hotter places.
For a performance car, a TMS is a requirement. Any non-actively cooled battery would either limit performance or melt. Both of which are unacceptable for something like a Tesla S/X/3/Y.
Nissan and Tesla are designing for different requirements. Are you interested in cheap and reliable, or in performance?
Nissan is making money on the Leaf. Tesla is making money on the S and X, and burning cash by the millions to try to start production of the 3.
If I had to bet on which automaker will be around in 10 years or 20 years, I'd bet on Nissan.
