Chomsky is a newspaper masthead font in the style of the New York Times masthead. This font is not an exact copy of the New York Times masthead. Rather, it aims to be suitable for running text as well, so it's used a larger stem size.
Chomsky font was created from scanned images, so it's legal to use. In the United States and most other countries, the design of a letter is not copyrightable, only the software used to produce it is. (Eltra Corp vs. Ringer, 1978; Adobe Systems, Inc. v. Southern Software, Inc., 1998) This font uses no copyrighted font software whatsoever, the author traced every character from scanned images, and included many of my own characters not found in the source materials (all the numbers except 5, most of the punctuation, the pilcrow ¶, almost all of the characters after Unicode codepoint U+00A1).
