The two links (above) don't lead to anything significant that I can see. The pages look like they were put together in a couple of minutes. The PDFs available just show a half-finished product. As much as I'd like to think that AM is going free, I am going to have to see something more concrete than what's available so far. Murray Hurps (if that is his real name) doesn't have a lot of credibility, not even in the Ad Muncher user community. Users have been ignored and misled for many years, so I guess I'll believe it when I see it. Don't know the man personally, but he has generated a lot of bad feelings with AM users, and many have moved on to other products rather than wait for a free version or a new version 5. I could be worng about this, but I've left my email with him for notifications, and we'll see what happens.
Nothing wrong with the product itself. It does a good job for everything from popups to advertisements (although not on https sites). I would not hesitate to recommend it.
