What Hacker News says?
Sure, if they don’t mind Qt automatically being relicensing under BSD “The little known KDE Free Qt Foundation makes sure that Qt stays free and open-source. It guarantees that all Qt modules currently licensed under LGPLv3 must continue to be available under LGPLv3 in the future. This covers all modules from Qt Essentials and many add-on modules. If The Qt Company discontinued the FOSS version of Qt, the Foundation…

HN discussionThe main problem with LGPLv3 is the anti-tivoization clause. That means you should basically provide the end user a way to replace the Qt libraries with their own. On embedded systems this can mean headaches for companies releasing commercial products. More details: https://embeddeduse.com/2016/04/10/using-qt-5-6-and-later-un... Qt from 4.8(?) To 5.6 offered an LGPL2 license too but after that it's mostly LGPLv3 i t…

HN discussion> An application using Qt Commercial must not communicate with any another application using Qt LGPL-3.0 or Qt GPL, if both applications run on the same device. This is more restrictive than GPL. https://embeddeduse.com/2023/01/06/using-qt-5-15-and-qt-6-un...

HN discussion> [0] https://embeddeduse.com/2023/01/06/using-qt-5-15-and-qt-6-un... That is an excellent link to a well-written article that untangles Qt licensing. Thank you! I have always found Qt licensing to be almost designed to be as confusing as possible. Unless you deal with Qt on a daily basis it could take weeks to understand what this article lays out clearly in one page. I've always considered the framework to be some…

HN discussionI have said it once and I will say it again: You really should think twice about buying Qt embedded licenses. Unless you really need an embedded version of Qt the LGPL variant is probably fine for you. Everyone who is saying that Qt is too expensive -> It's free. Just Use LGPL. All the tools are GPL but that doesn't matter if you don't want to link against those. The Libraries itself are LGPL so you can dynamically…
