So, it was useful and literally concrete piece of important information, then?

I see this as a radical open source movement. Some people hated to see that government was using Microsoft Windows and Mac OS X on their computers and decided to take the matter in to their own hands. Linux was forcibly installed on the computers and the suspect was caught seen masturbating in a dark corner as the progress meter went further and further.

So in your opinion you should be allowed to shout fire in a crowded theater, too?

Note that in this case it's about good censorship. Most countries on earth have these kind of pre-election rules to combat PR attack on the last hours of elections. Most sane countries have these laws. Since it's just 24 hours, it really just seems to ban it right before elections and is not some penalty on Google or Youtube. Google is intentionally breaking laws here and should be punished.

That you are
1) Breaking immigration laws by working while on a tourist visa.
2) Breaking laws by trying to get around the web censors and doing something not allowed.

Honestly, if you are just going to China to break their laws, why not just stay at home? If you still want to continue then don't break immigration and other laws in the country you are visiting. It's not only illegal but greatly distasteful towards the host country. They are welcoming you as a visitor and yet you are just going to be breaking laws.
