I&#x27;d need to catch up with what happened in the BMW i3 case to understand what your obligations are to people that don&#x27;t own the actual target device.  At minimum, you provide a link to a repository you control with the vanilla Qt source.  That should satisfy the requirement, right?<p>Installation of a modified library would seem (to me at least) to be a method you can share only with authorized owners.<p>I&#x27;ve released Qt products under LGPL, but they&#x27;re all industrial equipment and I&#x27;ve never had a customer give any of this a second glance.  They just want their shit to work.
