That would be the FUD

what does licensed software mean? If I have Qt commercial, do I always use
Qt under commercial license and thus cannot create any software using open
source qt?
Been hashed out on here many times. __Never__ fully resolved.
At one point the licensing was worded in such a way that if you were
using Qt commercial you could not use Wireshark, Doxygen, or any of the
OpenSource projects built with Qt. Visit the archive page:
https://lists.qt-project.org/pipermail/interest/ pull down the zipped
files for the past 18 months or so and unzip them into a directory tree.
Use Sublime Text 3, Emacs, or just plain grep to search for wireshark,
doxygen, and commercial in different searches. That should identify all
of the message threads.
There was no real resolution.
At one point the wording was so broad and vague that if anyone anywhere
at Intel had a commercial license, Thiago couldn't work on OpenSource
Qt. You will find that discussion in the archive as well.
Many of the companies I'm in contact with have either begun or completed
the abandonment of Qt.
For now my policy has been:
If a client wants me to use commercial Qt, it is their license on their
machine. Period.
The half dozen machines in my office have only the OpenSource stuff.
If you feel compelled to straddle the fence, then go onto eBay (or where
ever) and get yourself a ~$300 off-lease computer for your OpenSource
development and a KVM switch so you can use your same monitors and
toggle between two machines.
Right now that is the only way I have found to be "sure."
Study up on the alternatives because an industry wide migration appears
to be happening. One of the best known manufacturers of high end
video/audio products for concert halls, movie making, theaters, all the
way down to conference rooms and your own home theater dumped Qt during
the pandemic. As entrenched as Qt was there I didn't think it was
physically possible. They did it in under a year. That was the solution
they were forced into.
FUD + death-of-perpetual-license = mass-company-exit
