There's a difference, but it still strikes me as unreasonable to say that all institutional power must be leveraged towards political ends. I do business with a lot of companies whose owners don't agree with my politics, and I'd be unhappy to see them dedicate more of their institutional power towards fighting for things I don't want.
Yes, but it's not a political end it's an ethical end. Facebook is being leveraged by political actors to cause harm in an unethical way - wanting to prevent this is not a political stance unless you believe that being apolitical is adopting some middle ground between America's Republican and Democrat parties, in which case considering ethics at all is a non-starter since both parties have shied away from imposing any kind of hard regulation on Facebook.
Institutional power doesn't have to be leveraged towards political ends, but if you profit directly from an institution choosing unethical behavior in pursuit of profits then you are also behaving unethically. It's completely reasonable to apply that standard to the best-paid of Facebook's employees, just as it is completely reasonable for those employees to petition against committing more unethical behavior.
