In my country, we had been saying that the government was doing business with Israel, even though they were condemning on every public forum. It took only 1 journalist until the whole public saw the hypocrisy. 1 journalist against all TV channels and internet trolls. (Here 95% of all TV channels are sponsored by government).
I remember telling this years ago, yet this man, who also had to leave the country for his other journalist work said it at the right time with the right tools.
So, what I get this is, don't stop telling the truth. Even though nobody listens now, people will when the right time comes.
