As honourable as you guys are, if your network is compromised it doesn't matter.
Statement like these are, frankly, very low quality and add nothing to the discussion. It is just a worst case scenario that seeks to dismiss all opposition with no actual facts or legitimate logic to back it up e.g.: "What good is it if commercial aircraft have ACAS (traffic collision avoidance system), when the wings could just fall off! Or with a tiny fuel leak it could explode! ACAS won't help you then!!!"
I don't really have a horse in this race, but these arguments against CloudFlare are so low quality and thoughtless that I feel I must speak against them.
