This is a different issue. As I read the Perspecsys piece, it's about
protecting Russian users' data from the NSA etc, and not about censoring
online activity.
And the Nazi invasion of Poland was to protect ethnic Germans from Polish atrocities. The same goes for the Russian invasion of Ukraine.
I think Putin is trustworthy. His most trustworthy moment was when Snowden called in to his yearly TV show and he told Snowden that Russia does not spy on it's citizens like the NSA.
Let's take the word of a politician at face value, what could go wrong?
