Ok. API stability on the one hand, and keeping things maintainable and
un-bloated over a long time on the other, is of course a tradeoff. Different
industries will have different preferences, but the path we have chose for Qt
over the last 25 years seems to not have been completely wrong, even for folks
building safety critical systems.
That there are long threads on controversial topics is often a good thing. esp
if they are followed by code contributions from the people that care. Many of
the discussions we had last year about e.g. the APIs of container and string
classes (most of those on the development list where the development OF Qt is
discussed [1]) have definitely resulted in better decisions for Qt 6.0.

Well, over the past two years it became wrong because I (and others in
here) have been watching a massive exodus. Companies that were firmly
entrenched with Qt have now banned and most have completely removed it
from their product lines. Cable set-top boxes and medical devices used
to provide no end of high paying Qt jobs. Licensing combined with API
changes have the major players banning and removing Qt. The few
automotive people I have any communication with say they are also
looking at full redevelopment with RDK. Unless something drastically
changes, from where I'm sitting the only market Qt will have left at
year's end is phones.
By-the-bye, customers aren't going to hang out in the development list,
usually. The IT industry standard is to not delete things from an API
until customers have been queried. It has to do with keeping customer's
code maintainable.
At any rate, it has been a perfect storm.
Licensing FUD + death-of-perpetual-license + death-of-OpenSource-LTS +
Qt-6-rolling-out-incomplete + deleted-convenience-methods =

If you've already got to go through a full re-certification you might as
well jump to a platform that promises not to do that to you in the
future. There was no way the above math was going to lead to more
licenses and support contracts being sold.
Maybe Konrad is seeing something different where he lives? It sounds
like we travel in much the same industries. In America the stalwart
industries of Qt use appear to be abandoning it wholesale.
