alt Hacker NewsEveryone is quick to assert rights granted by the license terms and fast to say the authors should have chosen a better license from the start in case the license doesnt fit the current situation.
License terms don't end there. There is a no warranty clause too in almost every open source license and it is as important as the other parts of the license. There is no promise or guarantees for updates or future versions.
They're not saying they violated the license, they're saying they're assholes. It may not be illegal to say you'll do something for free and then not do it, but it's assholish, especially if you said it to gain customers.
