Voice acting is pretty important to the presentation of any game, and celebrity voice actors included as part of the marketing do happen. Voice acting can also be rather intensive and time consuming work that is often underappreciated. Not just anyone can do voice acting. Even live action actors can be awful at it. Anyone remember Peter Dinklage from Destiny?
So if they want better conditions...any royalties...go right on ahead. I much prefer good voice acting in my games to horrible voice acting. I'm glad we've got loads of VA talent working in this industry now. I still remember the dark days of Sonic Adventure and Shenmue's awkward delivery, Resident Evil's downright bad VA, and the SEGA janitors who must've done their House of the Dead games. I remember the days when MGS2's stilted acting was IMPRESSIVE, rather than just okay. Though I personally don't need stories and dialogue in my games to enjoy them, I much prefer that they be done well. So if some of the people want better conditions and royalties for their work, it's fine by me.
And since I'm not satisfied with my own opinion, here's an infinitely better one from Jim Sterling:
