When you file for bankruptcy, you give up certain rights to certain assets. Alcede forced the company into bankruptcy, and the facebook account at issue seems like an asset of the company, not Alcede himself (the facebook account is “www.facebook.com/tacticalfirearms,” not “www.facebook.com/jeremy.alcede.”) There’s no First Amendment issue here - the dispute is not based on what he is writing on the facebook page, but rather is a business dispuyte as to who owns the page.
but rather is a business dispuyte as to who owns the page.
From what you say, the page is not “him”. Rather, it’s the company. And the company has been taken over.
Does sound like a different issue... this is a corporate page not a personal page. Once it is taken over in bankruptcy he has no right to keep on using it, except as permitted by the court overseeing the bankruptcy. And definitely not to torpedo the value of the company.
