Very bad source. I go into why in more detail in this comment, but to keep it short: his numbers are lies and he knows it too - some of his screenshots are photoshopped to preserve his narrative. He has an agenda - an anti-Elon Musk agenda - and has no intellectual integrity.
Read around and that thread a bit and you'll see that people confirmed my claims and that those who doubted it and checked his numbers themselves observed a three order of magnitude difference* in his cost estimation versus their estimate.
This isn't a source to get informed by, but one that makes you delusional.
