As Walt states, there is a need of a pool of reserved frequencies for automatic or semiautomatic operation, in order to avoid clashing with others.
I have been a packet sysop since 1992, and it was the way it operated. Noone who is not a member of the forwarding net is welcome, even in packet, not to say anything of other modes. It is naive to stop a network because I am willing to chat on the network frequency. Rude as it may seem, it seems to be the only way for it to work. I see a fight against pactor...I don't remember seeing the same diatribe against packet. It seemed while packet was alive that the reserved frequencies were somehow accepted. Not the whole wide world has access to high speed Internet to bury "the obsolete communication networks" to convert them in chat channels. The sad fact is that anyway, it is happening. Another expression of the digital divide.
