It was an intentionally loaded question for the commentor I was replying to. I've used cloudflair services many times because they provide outstanding service...they are a company who consciously decided they wanted to excel in just a few things, they got very good at those few things, and they are still very good at those few things.

I speculate people are kneejerking against the notion of "putting all your eggs in one basket", whithout stopping to think that cloudflair's entire service offering is about spreading your eggs out across multiple baskets. And it's not like you're stuck with them - companies can and do partner with multiple cdn's all the time to diversify their peering arrangements.
