Beccara: It's not acceptable, Would you buy a house without know it's power setup? Waste connection? Could the house be a hippie solar only setup, Is there a septic tank?
The same applies to phone lines and broadband, It's not an excuse to bury your head in the sand about comm's these days, Like other 'essential' services that a house needs it should be looked into and explored before you buy/rent a place. You wouldn't have to go far either, Ask the agent/landlord if there is anything outside the norm with regards to comm's and then a quick call to Telecom would have given them what they needed to know
If the average Joe were to do their research, they would be told something along the lines of "The subdivision has been fed with fibre by Chorus, which is the future of telecommunications". And this would be true, but it also doesn't uncover the reality of the current situation. I guarantee you 99% of people building in these subdivisions don't know what BOF is or even what the UFB is, but they will be aware that their houses are being fed by "fibre" and would be under the excusable assumption that this is a good thing and nothing to worry about.
Again, look outside the square. Whatever way you look at it, it is not the fault of homeowners in modern subdivisions that they have ended up with WxC only and I understand their frustration.
