What do you consider „effective“? This will not change the law. It‘s about raising attention to a stupid law and that happens all of the time. Pastafaris, Birds aren’t real, … are doing the same thing. They confront stupid ideas by exposing them. If it makes a few people think about the issue, if it makes some aware of the problem, then it can be considered effective.

I don't know if it's what the GP meant but I would just be interested in knowing if it's effective in the legal sense, i.e. if a court would rule that it must be displayed despite not being in English.

It looks like it won't work in this case, but other examples of trolling where courts rule in favor of a literal technical interpretation would be funny to see.

I don‘t believe their goal is that a court would rule in their favor, though it would certainly be a great outcome for them. I believe that getting the governments lawyer to make up all sorts of justifications is what they’re aiming for, because that exposes how stupid this law is.
