As I'm getting more and more interested in releasing packages of my own in the future, I just read the LaTeX Project Public License (or LPPL). This document defines, among other things, the rules for
- modifying (TeX-related) Work by another author and distributing the Derived Work under the LPPL,
- transfer of maintenance duties to another author,
My intention here is not to stir controversy (to remain polite) or open old wounds, but I'm curious. I know there can be tensions between authors. For instance, the developers of Texmaker and TeXstudio (formerly known as TeXmakerX) don't seem to be on very good terms (see the bottom of this page).
My question, however, is specific to the LPPL.
Has there ever been high-profile public (legal, even) battles between authors of TeX-related work that arose due to non-compliance with the LPPL by one or several parties?
Those cases, if any, might serve as cautionary tales for aspiring authors.
Edit: I've chosen to remove my allegations of tension between Knuth and Lamport over the development of LaTeX, at least until I find a proper source.
