That is probably more a function that most new installs are on FTTN and incapable of providing 100Mbps. Anyone who wanted this level of service would be unable to get it. In fact Telstra, Optus and many other RSP have had to pay back customers that subscribed at this level but have never been able to receive it. So whilst your claims are factual, they are based on the mistaken idea that all NBN installs are the same.
