Your analysis seems correct to me.

Is it possible the qt-settings file is created by something other than
Octave on your system? Not that this is a bad thing, but it's also not
entirely well-supported, as we've now seen.

The 'news/allow_web_connection' setting has been present and has been
checked since the GUI was first introduced in 3.8.0, so it is not likely
that this was missing due to an upgrade from a previous version. It's
more likely that the qt-settings file was modified outside of Octave or
was created or pre-seeded by some other tool.

Do you think there is any remaining issue here, or do you consider this
resolved by fixing the configuration file on your end?

Or is the only issue here that the settings dialog implies that the
missing value defaults to 'false', while the actual behavior is to
interpret a missing value as 'true'?
