It's not a right to have them, but they weren't exactly a gift either. Square Enix is a company, a business, and Viera and Hrothgar are a product. An unfinished limited product.
I'm happy they exist, but I'm not happy that they're in a state where I can't even enjoy them because of how much I lose by switching to one. I'm not gonna be "grateful" for that. And I have zero obligation to be.
