That's why I didn't say "market dollar value" or "market value". The challenge is to ballpark a lower bound for the value that reddit has received from the mods over the years.
If you're dying of thirst and somebody offers you a glass of water some will argue the market value of that glass of water was zero. I get that. There's also the value of what that glass of water was worth to you and there are many ways to approximate that value. There's what you were willing and able to pay at the time, there's whatever water prices were at the time if you walked into a store, the size of a loan you would have taken out for it, etc. If for whatever reason this person gave you many life-saving glasses of water over the years, and you showed little appreciation, there may come a point where the two of you will debate the difference betwee market value and utility value.
I'm not trying to debate market vs utility value. I'm just saying if the mods have donated $100 of time over the years it's different from if they've donated $100 million of time over the years. It's an attempt to have a rational discussion about whether or not they're "throwing a temper tantrum." You're getting sidetracked because I'm using dollars to measure utility value instead of market value. If you'd like you can think of it this way: what would the cost of reddit's mods be if this was happening in a "perfect" market where other companies were competing for moderators.
> If it was so onerous and awful, they'd simply leave. Again, it's telling that not a single one has.
This should be covered in the first semester of college economics: if a company has no close competitors you can not assert that its employees must be happy because they haven't left. People have been screaming for months for a similar place to leave to, it doesn't exist yet.
