It's curious that when legitimate files, however obtained, that potentially harm the credibility of a person or organization are leaked, the first line of defence is not to address whatever the files reveal, but rather to attack the act of the leaker.

The other very tired aspect these days is to blame it on the Russians. This takes me back to a time long ago when the Russians were doing atmospheric testing of atomic weapons, and that testing was blamed for everything that happened, from the weather, to grandma's rheumatism.

How about:
a) not doing shady things in the first place, and you'll never have to worry about anything you do being revealed (it's called, living your life beyond reproach), and
b) if you are just too weak to do "a", then at least accept accountability when you're caught (but if you're too weak to do "a", you're also likely too weak to do "b"), and
c) spend some money and protect your systems against hacking.
