These savings should not be passed onto the consumers as right now it's a race to the bottom for the retailers
It is a race to the bottom which is excellent for consumers. If RSPs can't differentiate themselves in any meaningful way then they rely on price.
Good point. Before I joined an ISP in NZ years ago I asked if they had a USENET service. They did and I joined.
They don't now so I left them. My current ISP (Orcon) doesn't even offer an email service to new customers.
'ISP' in NZ means internet connection provider, not internet service provider.
