Considering that on paper these businesses all have employees serving as CISO, EVP-, SVP-, and many, many Directors of Security, I find it highly unlikely that the accumulated experience of the people and their teams results in decisions like this. It's hard to distinguish incompetence from malice in many situations but calling them "naive" seems to be indirectly excusing customer-hostile behavior. It doesn't make any sense to me because it's expensive to make sure your company's services are secure, but it's also expensive to not be secure. Perhaps it's less expensive to not worry about it because the loss-of-customers impact on revenue are still under the cost of doing it right. If that's the case it's a sad state for all of us.
