CATL are only offering the deal to EV manufactures who sign long term agreements to buy 80% of their batteries from CATL. "For whatever reason Tesla is missing out on this promotion together with many other CATL customers" is because they already produce more than 20% of their batteries themselves so can't be locked-in.
The question is what effect does this have on the price of graphite? Does the price of lithium drop to whatever CATL decide to make it or does every other battery manufacture look to make savings across their entire supply side/cost structure to compete? The EV market is very price sensitive. Time will tell.
Thankfully we have Tesla locked in on a fixed price for 4 years from their 2 off-take agreements. 8k from the first expansion and a further 17k from the 45kt expansion. The 2nd off-take will take SYR out to ~2030. As for the other potential off-takes, I think they're in limbo until people get their heads around what the fallout of CATL's machinations are.
