Well let's not jump to conclusions so quickly. Reading Facebook's report it states that their vulnerability was within a feature they developed. A smaller company is likely to have less complexity in their software. Less complexity == less chance of vulnerability typically. You can't be perfect. And you likely have less talented engineers than Facebook can afford, but if your software doesn't provide these sort of bridges that Facebook developed then that's one less point of exposure you're testing/fixing/securing.
