John Linton was Exetel's founder/GM. A very honest guy but more interestingly he has written a daily blog for years which is brutally honest and gives a very interesting insight into tech/Internet pricings and inner workings. More importantly, he continually strived to make their plans as cheap as possible within reason and to cut costs using different methods. One of the funny cost cutting measures has been to tell out of contract unprofitable customers to take a hike. Call too much, use 100% of your allocated plan allowance, etc and you are culled. Respected TPG but pretty much hated all other ISPs, NBN, and the government (which isn't hard).
A true bargainer.
There will be mixed feelings about this for anyone who has dealt with Exetel.
