Re: @gnasher729 - Am I missing something ?
Hmm, no. GPL lets you use the licenced code to do whatever you choose to your users, unless it relates to the code and software itself.
Which is why you can embed Linux in your weapon systems, or use GIMP to create advertising, or use ADempiere to manage your Uighur re-education camp.
That's the thing about freedom. To enjoy it you have to accept its downsides.
