thank you for sharing your perspective and for your important work on
the KDE Free Qt Foundation. Some comments inline below. For the
avoidance of doubt, I am speaking here as a representative of KDAB.

All of these, including the first one, are worthy and important goals.

This is very important for commercial license holders (including KDAB)
who have a grey area of potential breaches of their commercial license
terms through the development or use of Free Software alongside their
commercially licensed use of Qt.

It is very disappointing to us (KDAB) that there has been no further
clarification on this since the announcement.

The existance and functioning of the Open Governance model of Qt is
critical to KDAB's business and critical to the continued success of Qt
as a technology and a business. If Qt Company were to delay Free
Software releases by the maximum allowed by the Free Qt Agreement, KDAB
would be prevented from contributing under the Open Governance process
to the Qt Company maintained Qt tree and would thus contribute to,
support and sustain any community-driven Qt repository that follows the
Open Governance process and spirit.
KDAB would also ensure that releases of this repository of Qt, developed
under Open Governance, would be available freely, in source and binary
installer format for the modules and platforms with sufficient interest
to sustain such activities. Additionally, we would work with our
customers and partners as well as the rest of the ecosystem to ensure
that these releases are commercially supported globally for an extended
period of time.

Obviously not. KDAB has always considered itself, and still considers
itself, a part of both these communities. Their health and sustained
access to Qt under Free Software terms is a corner stone of our business
and our 20 year success. We will protect it as best we can.

We also hope so.
