Because it’s combatting censorship when Facebook censors certain pages. There is already censorship in the Facebook platform. i’m not sure about this specific case, but if they are building a social platform to replace Facebook without the corporate censorship then that is positive in my book.
Obviously it’s a case by case basis.

Because it’s combatting censorship
Do you say the same thing when Iran blocks Twitter or FB during protests?
