This is a good thing!
No, wait, let me explain that statement.
If governments are forcing the hand of the big multinational companies then those companies will have little choice to remove the end to end encryption since one product will not work in all countries.
We tend to use the biggies through laziness. It comes bundled and our friends us it. Without the proprietary biggies, the public will then turn to open communication platforms following open communication standards that no country can control. There will be dozens of different clients available from authors around the world and no country will have the ability to shutdown all the individuals who wrote those clients.
A country may be able to threaten a user, but then the (innocent) user has the option of handing the government their previous conversations (but you'll know they have them!).
OK, I'm not really saying the Russian law would be a good thing (or the Merkin, UK, or any other government back door). But maybe if someone points out how simple it is to circumvent then perhaps common sense will prevail (facepalm).
