The role of organized labor is to advocate for workers who want to organize. I don't think it's reasonable to assume that something must be wrong with a company simply because it doesn't have a union.
I didn't intend to say that something is wrong with a company if its employees are not unionized.
I did intend to say that a union can be an effective tool in advocating for employees to an organization that is driven to maximize profit.
For profit companies are often rewarded for minimizing costs. Certainly one can envision that FB might view moderation teams as an expense rather than strategic investment.
Organized labor can be a good counter balance to that.
