@evan Yeah. I’m sure the “we and only we can monetize” played a role too (especially at the exec level), but many rank and file genuinely believe a story that goes something like: 3rd-party extensions require data access; data access to FB-like data (more sensitive than Twitter!) at FB-like scale means some 3rd-party will inevitably abuse; FB will inevitably get blamed for that abuse no matter what safeguards were in place; so the risk is too high. And that is hard to argue with!
