One post in 28 years is possible. I have about that much time with Cakewalk and I have not posted in the forums for almost a decade. I only ended up here because of the new subscription email and had just about the same reaction as the initial poster. Of course, I've calmed down quite a bit, but for old timers like us, this is a bit shocking at first.
I don't think it is wise to have such a strong reaction and to throw the "BYE" card out there because the boards here and at most other software sites represent the tip of the iceberg in terms of the user base. It makes it seem like the site might be too much of a fan boy accretion.
From the short while I have been here, I have found the forum user base to be very helpful. It would probably be best to tell the poster to sit back and cool off for a while. Give it time for the idea of change to sink in ... you can pretty much go on as you have with this subscription scheme even if there is a real bump in annual expense from previous incarnations.
