As usual people want more than is offered. This is human nature and I should imagine occurs frequently by parties either side of the fence. It certainly does in the commercial world. Those who succeed are the ones who do not push too much. It is no point in squeezing the supplier so much that they no longer can afford to supply you - afford does not just apply in monetary terms.

I hope that those using "free" services realise that they may have to organise smaller units of works and plans for redundancy of supply as the true "cost" of this.
