| They do acknowledge the source of the font: "Hack has deep roots in the libre, open source typeface community and includes the contributions of the Bitstream Vera & DejaVu projects." It's a bit disingenuous though. I'd call Hack a straight copy of Deja Vu Sans Mono, with a few very minor tweaks. On Linux using the TTF fonts I can't even see a difference in line height: http://i.imgur.com/wxTr0at.png http://i.imgur.com/OO1bJFE.png The only glyphs I can tell which are slightly different are 'i', '0' and '_'. |

Aside from '_', 'i', '0', many of the changes are so minuscule that it feels more like a change for the sake of change. Some however are nice, like the parenthesis placement, cleaner 'r'.
One thing I really don't like is the change to a serif-style comma. They've probably argued that it improves readability, and prefer that over typeface consistency.
They should emphasize more the previous work they are using, otherwise they might come across as ... hacks.
I'll probably stick with inconsolata though. But good job, nonetheless.
