I mean it's hardly the end of the world if they do, it's not like you pay money to grind relics (....or at least you shouldn't be), plus you can also get some niche pieces out of it for characters like Aeventurine of Bronya.
Didn't some other game recently get caught secretly making it so people who were big spenders already had lower drop rates on limited characters, and they got caught because the drop rate actually fell to 0?
