Troy does make an interesting point about other industries not using the Pro only model. Of course some do not need to, the cost and time resources required to access some items makes it an efficient barrier but ultimately the business owner can choose to set the rules for his or her products. I have questioned many things about OPT decisions in the past. Ron and his predecessors have engaged with me but still it all comes down to Dr G can set whatever rules he likes. There may or may not be a lot of profit in opening up a particular market and presumably Dr G weighs up the risks and concludes with a certain strategy which I guess is what he is paid to do.
The only thing I fundamentally disagree with Troy about is the use of a green font, not on aesthetics grounds but because it is damned hard to read. On the plus side, I did enjoy your Youtube videos.
