In fairness to flock, they just hired a CISO and are actively recruiting for a head of product security and privacy as well. So I'm not surprised they're dealing with some of this.
Edit: I'm standing by it. The person they hired for it has a good track record elsewhere. And much as I don't like what Flock is building as a company, at least they're building security in now, even if it wasn't front of mind for them in the past.
He's got his work cut out for him though.
