What Riot is doing here is called blame-shifting. They are making it appear as if they are supportive of their employees wishes whilst intentionally ignoring the bigger picture --- what caused the walkout in the first place. More or less "It's your fault. You agreed to the contract. All your fault. Not ours. That one's on you. And since it's not our fault, we aren't going to change that part of the contract. But if you wanna walk out NOW, we'll be accommodating because we **just** love our employees."
It's a business thing. Politicians do it too. It saves their image time and time again.
