I haven't seen any notable number of people giving a counter offer to the proposal of Reddit. People "agree that it should not be free", but are unable to give any number of what they think it should cost. All we know is that the proposal, which averages at around $2.50 / user / month is "outrageous", bearing in mind that this allows to browse Reddit fully ad-free, denying them of that revenue stream.
I really don't know how people expect Reddit to make money; they apparently don't think the service is worth $2.50 / month, but they seem to forget that Facebook sells their data for 20x that amount.
