It seems to me that this post was the last straw in the appearance of that proposal. This question has been raised before:
There were talks for a long time (and later: Bandwidth payout for node more than price user pay for, how it possible), but after such a massive discussion, it became obvious to everyone that it was time to do something, it was impossible to delay an unpleasant decision any longer.
So I wouldn’t call this discussion as a warning, but more like a concern. And thanks to our Community, we were able to gently begin the process of finding a point of sustainability for the economic model.
