There is the logic of polarisation, of fight - both sides use whatever comes their way to weaken the opposite. Russia wants to weaken the USA, so they expose the political dirt to destabilize, and that works in the short term - but I like to think that in the long term it removes the dirt and makes the free system stronger.
The same thing: https://stopagitprop.com/2016/08/13/exposing-edward-snowden-... - it escapes them that sometimes to reform and to make the system better in the long term you need to weaken it in the short term.
Update:
And yet the same thing with the ex-soviet spies (for example https://www.google.pl/search?q=ex-soviet+spy+youtube) who defected to the west - all they see is the destabilisation caused by the western activists - they don't see how the whole value of the west is based on the improvements that happen because of the activism.
And this is not to say that there is no danger of destabilisation - it is a dangerous thing - as we have seen in the Near East recently. But we must face the danger with courage - because giving up the freedoms would make the western system the same as the other side. And it is probably not as dangerous as the dictatorship agents thinks it is. The dictatorships have a lot of internal tensions - if the dictator looses grip - it all goes boom - but in a democracy the tensions are released in small portions - by the activism.
