The owners of Lancer could be chill, but unless I am mistaken, copying rules straight from a book like that is frowned upon without some sort of agreement.
Similar to how the Shadowrun character generator Chummer cant list the description of qualities, spells, and the like, but provides a reference page to look it up.
Or similar to Solasta can only use certain official Dnd5 subclasses due to WotCs policy.
I'd love to be wrong, but that's my understanding of these sorts of things.
