I was around for the leap from BBS systems to Fidonet; the bad old days when there were no such thing as graphics. I can absolutely sympathize with what's being said here, and for me, there are two primary reasons why I pine for the elder days. The systems then required some effort to gain access to which kept some of the signal to noise loss down (if you know the difference between CB radio and Ham radio, you know what I'm saying), and while commercialism's always been a part of these systems, more value was placed on content than advertising.
You and me both, and that became a cycle with each new generation of technology. I remember that FidoNet (and Usenet, for that matter) had a lot of that ham radio ethos, with commercial messages most unwelcome. But once the internet got too big, Usenet drowned in spam. It was too easy to crapflood newsgroups into oblivion, and once the politicians started grandstanding, ISPs wasted no time nuking their NNTP servers.
