This is a feature, not a bug.
The bug was the fact that it was only two groups of people figured this out.
Nobody improperly took anything from anyone.
This really only shows how much the lottery is an innumeracy tax. There was nothing hiding the fact that you can safely risk more and win more -- everyone had full access to this knowledge -- it was published right at the place of purchase. It is not like it was some insider secret available to only to friends of some corrupt programmer or something. It took him only 3 minutes to figure it out. You or I could have done the same.
So, totally fair.
