'cause most people would not be able to read it and would relegate the game/site/project/... as something tailored to the 130 million (or thereabouts) of more than 8 billion people who do read Japanese and most likely sideline it.
Cerebras claims they have extremely high demand, presumably from enterprise. So I assume it just hasn't made business sense yet to open up higher tiers to small customers.
Saying the financials are terrible is a bit of a stretch. Rapidly growing revenue, decreasing loss/share and a loss/share similar to other companies that IPO'ed this year.
The more concerning thing is just not having diversity of revenue, since most of it comes from G42.
The point is, there are IPO shares available to sell, even to people who have never expressed any interest in the company. That never happens if there's genuine demand for an IPO.
