Hi,
That is not the question that was originally asked.
The question was about some developers using commercially licensed “Qt for
Application Development” product and other developers using Qt Creator under
open-source license. This is not allowed, because the license agreement of Qt
for Application Development does not allow use of open-source versions of its
contents in the same project (and Qt Creator is part of Qt for Application
Development).
Yours,
Tuukka

"This seems to become a longer thread than I envisioned, as apparently my
original response was not clear enough."
As I pointed out - it's because you're not answering the question that was
asked, and therefore confusing the issue.
"Is it still possible for the developers who don't use Qt libraries in any way,
use Qt Creator IDE for editing and debugging?"
The answer is yes.

In general, if there are any questions or concerns related to licensing, check
the FAQ: https://www.qt.io/faq/
If you are looking for advise on licensing, I recommend either to read the FAQ
or consult a lawyer. While everyone here tries their best to give good advice,
it is possible that some incorrect information or interpretation is presented
(because licensing can be a difficult topic).
Anyways, I'll now explain again the answer to the original question asked. The
question was, as I understood it, "Is it allowed that people working in a
project use commercially licensed Qt and some other persons in the same project
who do not develop Qt use open-source licensed Qt tools?"
Answer to this is: No, it is not allowed to mix commercial "Licensed Software"
and the open-source versions provided by The Qt Company in the same project.
This is a restriction coming from the commercial license agreement:
https://www.qt.io/terms-conditions/
The basic rule of thumb is: Don't mix. Use either only commercial or only
open-source versions of items provided by The Qt Company.
Yours,
Tuukka

The only difference that comes to mind is that the first group can use
Qt Creator under its commercial license, which may come with some extra
features (not exactly sure of which ones, at this particular point in time).
The second group can instead just use Qt Creator under its open source
license. The open source license of Qt Creator itself does NOT extend in
any way to the software you develop (cf. the GPL FAQ).
