While I won't argue that Fibre-to-the-cabinet (FTTC) is better than Fibre-to-the-premises (FTTP) it is, at the very least, much cheaper.
The cost per consumer for "last mile" connections can be an order of magnitude more than those used in the core network because of the economies of scale at play. [1]
Is it cheaper? It depends on how long you expect your investment to be relevant for. If you accept that FTTH is going to be an ultimate 'end game', at least for the foreseeable future, then going FTTC is not cheaper. It may require less capital investment today than FTTH, but in 5 years, you're having to invest a similar amount all over again, in new equipment or by going FTTH.
FTTC is just delaying FTTH.
