I'm curious, why do you think that these requirements won't spread to the rest of the internet? I doubt the proponents of this law would create a "loop hole" by allowing other sites to maintain "anonymity" (in quotes because there's no real anonymity on the internet for almost nearly everyone).
Also, you seem to be making two contradictory points:
1) Facebook and Google pushed hard for verified accounts
2) Some parts of the internet make it optional to reveal your true name
Verified accounts, as I understand them, on the social platforms are only for people who publicly want to build a brand around their identity. While people have to use a "real name" on Facebook and Google, there's nothing requiring to get verified.
