Ello's charter makes it legally impossible for it to display ads

Today it announced that its advertiser-free status will be permanent, since it’s becoming a Public Benefit Corporation. Under Delaware law, a PBC is a special kind of for-profit entity that is legally obligated to consider the public impact of its actions. As such, the company has drawn up a company charter that bars the firm from ever selling user data or displaying ads from a third-party entity – and the company isn’t allowed to sell itself unless the buyer agrees to abide by these rules, too.

Interesting. Maybe I should check it out.
