The private script section:
https://osbot.org/forum/forum/334-private-scripts/
I would think that private scripts are preferred for high-level content as realistically not that many people can fund the accounts to farm using this content, and normal users aren't going to risk their only main account.
More money (and peace of mind in terms of knowing exactly how many people are using the script) to sell to a single user or group of users on high-level content private scripts who can afford the higher price and to fund the accounts to utilise them.
That's what I would have thought, maybe there's another reason
