Well that 'confusion' is between developers and there are many other business tools out there with similar names which from the perspective of an average customer, they will still use it and won't care about a name clash with a decades old developer tool used only by software engineers.

For the majority of businesses looking at 'Screen' now, they won't bat an eyelid and will use it along as it 'just works' no matter the name conflict. If they saw GNU Screen they'll just say 'What's that' and forget about it.
