I know several people who have completed their Masters Degrees through Athabasca. For mature students who are capable of a good deal of self directed learning at the University level, then it's great, if not, then the complaints you've heard will likely apply.
From what I've understood from those I know who have used Athabasca, typically experienced learners flourish with the style and direction of the course work/load. Those with less experience or with a more "lax" learning style in University with respect to self motivation will have a higher chance of struggling and/or wasting their money.
