One way to solve it could be to pool the revenue and to position Tsu like this: "90% of revenue goes to a good cause of your choice (climate, humanitarian, etc.), not to 1 huge corporation"

Edit: Every profile would then get a "I Donated $x today" badge (visible publicly) as a feel-good engine. You could then convert the amount to real things like "I paid 2 meals in a 3rd World country today" or "planted 3 trees", depending on your choice of the cause.

How about I generously offer you $1 per month? Feel insulted? it's exactly Tsū's plan.

(consider fb has 1.3b users and it's q2 earning 2.9b, $1 per month is indeed a generous offer)

joke aside, the fact is, when you talk revenue sharing to users, they/we always over-evaluate ourselves, and you can never match the expectation.
