Well, you can get round the monetary compensation by saying that it isn't "primarily intended or directed towards". So if it isn't intended for that purpose, then the issue re payment doesn't apply?
If it does, then the point would be the consideration of compensation - if it is effectively money to pay for something of which afterwards you own the full value of, as such there is no depreciation or appreciation in terms of the product when purchased, er go, to me, there is no compensation. Though I know very little economics.
However if there is an "admin fee" to make it possible, is that compensation? I guess that depends on the size of the fee, and perhaps founding articles / company type as Fred covers; though I was thinking it could be possible to argue outside of company structures, as the "We are a charity" card seems a bit sleight of hand.
Also - to define cost price - I buy 100 imaged CDs of OER from a CD manufacturer for 100 pounds, so cost price to me would be 1 pound per CD - again see "I know very little economics", but this would be my argument for avoiding "profit". The admin fee would probably move towards direct cost as a model, but I think in moving this way the problem with commercialism occurs.
