I cannot say that I have ever read any such thread about it, remember, ive only been in the LFS zone for about a year.
The main reason why I started this thread was because I was linked to a cheat that is about. I added the contact user that uploaded the cheat, and he is a demo user.
So, if people had less time on the demo - they would not have the time to create the cheats, as such.
Yes a S2 user could program the cheat, but if they really did,and was caught - the S2 licence could be revoked.
A business plan yes, but I think is a bad one. I know for sure, that I have played a few time-based demo's, and have ended up buying it.
