The problem you have is "what is a growth market", especially over time
as it stabilizes and see new entrants, but growth is now in a phase
where you need massive scale to keep playing.

You then shift from a "sales are guaranteed Day 1" to a "build it and
hope for the best". Many Commercial get fearful at that point, because
of the temptation to link capacity to guaranteed sales.
