Closing things down is the argument taken to a logical extreme. Could they function without collecting that much PII though? If you can't do it right, don't do it, is far more reasonable when limited to just the collection of PII or other potentially sensitive information. Some identifying data might be absolutely required of course, but the great many cases like this show that collecting the absolute minimum must become the default choice.

If you leave your car unlocked and police detects that, they can confiscate your keys and probably even fine you after you collected them. The same principle applies to everything. To a certain extend, it is your duty to secure things. Just putting a sign there "please dont fuck with me" isn't enough these days.
