As people point out in comments below, the law does no such thing. It doesn't prohibit storing user data outside of Russia, so it doesn't offer any privacy protections whatsoever. What it does is require that data to
also be stored inside Russia, where it is subject to warrants (and warrantless wiretapping under SORM-2 and similar arrangements). Which is really everything you need to know about the purpose of the law.
Speaking more broadly - yeah, Russia is an authoritarian populist regime with a known penchant for human rights abuses and suppression of political dissent. And so it's going to be judged as such when it does things, not equally to any other country. This is similar to how we judge people differently, and ascribe different motivations, based on their past actions that we know about.
