Commercial font piracy may be a problem. Sure, whatever.
...
Technically speaking, consumer font piracy might also be a problem. But when the fonts in question are not actually marketed or sold to consumers, it is evident that the creators don't care.
e.g. I highly doubt Amazon cares or is affected when Bookerly gets extracted from current Kindle firmware and sideloaded onto Kobos.
Sure, they will probably go through the DMCA motions if it is flaunted on download sites.
But it has no impact on them if someone does it themselves.
In fact, Amazon distributes the fonts in their freely-downloadable-and-openable firmware.
..
So if the fonts in question aren't being marketed, it's not that I don't agree it's piracy, but... why should anyone care? Unless someone is trying to use your servers or forums to wave red legal flags, that is.
Then again, I don't care much about fonts -- I'm happy if they let me see words on the screen.
