Investors don't mind bugs as long as the money keeps rolling. Customer experience is a far second.
Truth is nobody cares for customer...
In software industry, cost of bug is mostly nothing compared to other industries like construction. Products are not always life-crucial. One person with laptop can build you product. In this context, engineering itself is secondary. Decisions are made on hype, not on reasoning.
But no, obviously not. Obviously it's bad engineering then.
