Re: I must express my opposition to this
It may be reluctant, because he's probably saying "I do not want to lose the company's protected status with respect to liability"
Are you misunderstanding §230 of the CDA? It was passed specifically to protect information services from liability in general for external content, AND to allow them to edit or censor some content without creating such liability for all content. Short of the law being changed, nothing Facebook do or don't do can create liability or remove the protection. (Obviously there are exceptions, eg for illegal content.)
