clarification on supported document formats?[edit]

A request to the community and to ArtifexSoft: MuPDF does — or did — support some additional formats, such as .cbz/.cbr (Zip or RAR-compressed ComicBook, though not .cbc [ComicBookCollection] hierarchies) and FB2 (the version from Ubuntu 22 which I use on my tablet does), and it seemed MuPDF did at one point intend to support FB3 in the future, too. If it still does any of that, please state it in the article, and if it doesn't, please state that *also*.

Palm lawsuit[edit]

It seems that some editors disagree with the statement that "In 2009, Artifex Software filed a copyright infringement lawsuit against Palm, Inc. for violating the GPL when it included MuPDF in webOS, claiming that the GPL only allowed for "non-commercial use."" However, it's pretty clear to me that that is in fact what the lawsuit is about. Paragraph 15 says, "... Artifex offers MuPDF ... free of charge, under the GNU General Public License ("GPL") for non-commercial use." However, if it is in fact offered under the GPL license, Artifex can't restrict it to only non-commercial use. Then in paragraph 16, "For those seeking to commercially distribute MuPDF, or any product that incorporates MuPDF, Artifex will grant, for a fee, a license to ... MuPDF." Again, they imply that commercial distribution will require payment of a license fee. Finally, in paragraphs 26 and 27, "Palm contended it was using MuPDF in accordance with the GPL and was thus authorized to use MuPDF without paying Artifex any royalty or fees." "But Palm's claims were lies. ... Instead of paying Artifex a reasonable licensing fee, Palm wanted full commercial use of Artifex's software for free." Another implication that it wasn't possible for Palm to use MuPDF commercially under the GPL.

Then in their response, Palm's lawyers also thought that Artifex claimed that GPL doesn't allow commercial use. In paragraph 15, "Defendant denies that the GNU General Public License permits only “non-commercial use.”"

So, I think that line in the article should stay as it is. Just saying that they filed the suit because "licensing terms were not upheld" isn't particularly informative, seeing that the sentence already says that the suit was "for violating the GPL." 2602:304:B1B8:F420:7C30:CFEE:53A5:6618 (talk) 07:10, 3 May 2013 (UTC)[reply]

Also, as was noted on Slashdot when the suit was filed, Palm did include the source code to both MuPDF, and to the PDF viewer app that uses MuPDF, as the GPL requires. So that wasn't what the supposed GPL violation was... 2602:304:B1B8:F420:7C30:CFEE:53A5:6618 (talk) 07:18, 3 May 2013 (UTC)[reply]

The source release from Palm only included the source code to the mupdf library. They never released the source of their PDF viewer that used the mupdf library. That was what the GPL violation claim was about. 94.254.94.176 (talk) 09:12, 5 September 2013 (UTC)[reply]

As the comment you replied to mentioned, "Palm did include the source code to both MuPDF, and to the PDF viewer app that uses MuPDF". It's the documentserver.tar.gz linked to in the Slashdot discussion. — Preceding unsigned comment added by 75.27.143.66 (talk) 16:23, 7 December 2013 (UTC)[reply]
