That's actually a pretty good illustration of my point. Because Facebook has many of the rights that people have (own property, enter contracts etc.) but very few of the liabilities (can't be imprisoned, rarely ever pays any fines in practice), Zuch can use it as a proxy to do a bunch of shady stuff, that he wouldn't do if he risked being held personally liable for it.

If companies as a legal concept didn't exist in their current form, then we wouldn't have this problem of one person, or more commonly many people, using them as a proxy to get away with a bunch of unethical stuff. Often way more unethical that whatever Facebook / Zuck is doing, such as destroying ecosystems, prioritizing profits over worker safety, etc.
