LGPL v3 is incompatible with GPL v2
I've been a contributor to MuseScore, which is GPL v2 licensed. In MuseScore 2, I used Adwaita icons, unaware that GPL v2 and LGPL v3 and above are incompatible. (In MuseScore 3, I now use an old version of the Material icon set, which used to be licensed CC BY.)
There are other projects that violate the LGPL v3 license — GNOME Clocks, for instance, which is GPL v2 and above.
Would you consider relicensing the project to be LGPL v2 and above, rather than LGPL v3 and above? (Or adding yet another license — GPL v2?)
