I can't do anything about iran, i don't live there, neither does anyone else commenting here it seems... but many of us do live in EU, and are bothered by EU doing the same thing as iran, even if it's on a smaller scale (for now). You can't support censorship at home and then act outraged when someone else just implements more of it... even though some do, as long as the censored things are the things they personally don't like.
To be fair, i'm more worried about UK, since it's a "test ground" to see how things work before the bad thing are implemented elsewhere, but either way, in my small country we have a saying, that "people should first sweep infront of their own doorways", and yeah, EU and our censorship is my doorway in this case.
TLDR: if we're bothered by internet censorship, we should first stop at 'at home'.
