Since I have a mixture of both open-source software (some of which I actually paid for, to support the development effort) and traditional proprietary software (for which I do have the licenses -- I keep them in a safe place), I'm not one of those people.
But, let's do the math: a few dozen applications, we'll call it 36. Divide that into $100K, and you get approximately $3k per infringing application. There are a few software products that exceed that price, but the list of vendors in the list you provided don't appear to fit that criteria (unless it was enterprise software from Microsoft).
So I'll ask again. How is that fair restitution?
