Stories like this hit home. Overal, I'm glad they got caught and I hope it serves as a warning to others. Fonts are intellectual property just like all copyrighted software. Stealing fonts is stealing. Period.
I just wonder how nobody knew they were committing a sin. Sounds like what we call grand larceny where I come from. Paying up retroactively isn't good enough for me. If I find out they were stealing my fucking software I'm calling out the lawyers.
