Gardimuer, the rub, so-to-speak, is that Wikia is a business. In that context, they will act to defend their business interests. In the case of Wikia, this protest likely allows users to continue browsing content because Wikia depends on advertising for its revenue to provide a free service to those who use it (or if not the sole reason for it only being partial, then a contributing factor). The bonus is that morally, Wikia's in the right, while still defending their revenue.

If you were paying for Wikia's hosting, it'd be a whole different story and yes, it'd be highly inappropriate for Wikia to do this.
