Well, usually those lifetime licenses are hugely discounted, so chances are you didn't lose too much money. And to be fair, if it's a new company (not a start-through) they have to get money from somewhere. Old customers are first point of contact
I had the same with Ad-Muncher, suddenly they made their product 100% free. So on the end of the day... We should be lucky these 2 great tools are making a comeback. Just as their torrents...
Peace!
