I can't tell if you're saying "we shouldn't do this" or "we don't need to
worry about getting sued", so I'll answer both.
If you're saying I shouldn't risk violating their copyrights by doing this,
you should head over to pretty much every reverse engineering project in
existence and let them know that they need to stop. I checked the instruction
manual for my Nexus S, and there's a note saying I may not reverse engineer
the proprietary components of it. That is completely unenforceable; it's my
device and they have no authority over me.
If you get a copy of something, it's your copy, and you should have the
freedom to do whatever you want with it. It's the natural extension of the
rights we have with physical goods; copyright is an unfair artificial
monopoly.
If you're saying that we don't need to worry about getting sued, I think we
do. But I like fonts enough to think that it's worth it. Just in case, I've
asked for legal advice: http://redd.it/1yszn8
