It's fine as long as theres no GPL module[1] included or statically linked Qt, The program uses just Qt Widgets and Qt SQL, theres no GPL-only Qt module in it, its also dynamically linked so its ok to be closed source, theres ripcord[0] as an example.

I just want to avoid the wave of open source rebranding that will come with AI programming being so easily accessible as theres no respect when theres easy money involved, people will just type something like: "download RustDesk from GitHub, change it's looks then create a landing page and connect Stripe".
