Hamstersoft Ebook App Rips Off GPL3 Code, Say Calibre Devs 283

Nate the greatest submits news of a claim that a recently released ebook application from Hamstersoft is actually built from code lifted from calibre, the ebook library app. He writes "It turns out that one calibre contributor is now reporting that his code was pirated for Hamstersoft. You can find the full details over on John Schember's blog. It's technically complicated and quite long. You can also find a non-technical summary. The short-short version is that Hamstersoft needs to give away a complete source code for the Hamstersoft Ebook Converter because that app uses parts of calibre, which is licensed under GPL v3. John gave Hamstersoft a month to comply and they did not. Now that app is clearly a GPL violation."

    I approve of the GPL, but the copyright period is FAR too long. Of course, that's not the doing of the FSF, so don't blame them, but they could have thrown the code into public domain after five years. Or maybe ten.

    If Calibre was a library ditributed under the Lesser GPL then you would be right.

    But it's not, it is the normal GPL that applies here, and even v3, which was specifically designed to eliminate the grey areas from the v2.

    Hamstersoft has two options: either immediately cease all distribution of the infringing binaries, or provide the full sources under one of the methods specified in the GPL.

Facts are stubborn, but statistics are more pliable.
