Because for Wall St capitalism, dominance is the product.
Which is why steady-but-slow niche businesses don't get this kind of attention, even if they have better long-term prospects.
The product being sold at IPO is the promise of dominance of a market - because that implies a whole set of predictable relationships with investors, employees, and customers.
The product as sold to customers - whatever that is - is almost irrelevant.
A successful IPO is a convincing statement of political intent. We has almost managed that - but not quite enough to get it over the line.
