And the thing is, there are open source internet browsers that can be written to avoid any browser checks that a law might require.

However, if Google's browser DRM gets widely implemented, a browser-side content blocker would be effective, because all those open source browsers would be unable to access the wider web.

I think if Big Brother Browser with Google DRM is our future, we're going to see people using 2 browsers as standard. They'll have one "corporate" internet browser, for Instagram, Amazon, whatever. And one "free" browser for all the grey area stuff.
