While title is click bite, they do say right at the beginning:

*Right now, it is pulling through only because of Microsoft's $10 billion funding *

Pretty hard to miss, and than they go to explain their point, which might be wrong, but still stands. 700k i only one model, there are others and making new ones and running the company. It is easy over 1B a year without making profit. Still not significant since people will pour money into it even after those 10B.
