Adding Y to Xy is already a tough sell, but when the upgraded Y costs more than all of Xy? I sympathise with GP. GitHub can do it from an economy of scale and probably 'should' be more expensive, but it can manage not to be (maybe cheaper is actually optimal, given how many more will pay for it, point is it's in some sense 'worth' more) which puts OP in a tough spot.
Imagine trying to sell a better WYSIWYG editor for WordPress for example. You can be better, save time, etc. - it's still always going to be a tough sell to charge more than a fraction of WP itself which offers a WYSIWYG editor and everything else.
