Can you rephrase this as;
"I'd like to see a model where I can pay a lot, and thus allow 10 other users for free" ?
How about something along the lines of "it costs $10 per useful per month to make the platform sustainable. A subscription is $100. When you subscribe you pay to keep 9 other users on a free account."
In other words, my question is, are upu in the 10% paying for everyone, or are you in the 90% getting it for free?
