On the surface of it, yes, but at least in the Qt case, the Qt Company is exempt from obeying the GPL by requiring contributors to assign them copyright, effectively making the codebase permissive for themselves and only themselves.
Both MySQL and Qt are licensed under GPL/LGPL, unless you pay for a commercial license. So, if anything, they are examples of copyleft licensing.
