I know something about government lies and I can even list a few of them.
When I started getting into bitcoin in 2014 the government discouraged any involvement. The official stance was that if you run a company dabbling in bitcoin, you're most likely a scammer. They wouldn't shut you down but make your life miserable by issuing warnings, putting you on lists of dangerous companies and so on, all to protect investors. They'd make it hard for people to buy crypto by asking banks not to process transactions. They'd issue a lot of different opinions about tax laws regarding bitcoin, for instance the chief of one tax office would say something and 6 months later his superior would say that the guy was wrong and you should file this or that. At first they said it was intellectual property, then a collectible, then a stock, then finally a commodity.
Anyway, years later when most companies shut down or moved and people had to switch banks for the third time because this would not allow you to send money to an exchange an another would tell you there's a limit for crypto transactions, the government said that since you guys have so much money from bitcoin it's time to share all that and we want 20% so finally, after 10 years we have real tax guidelines for you.
Not all countries or governments tell everything to their subjects, because if the government knows something that is not good, they will keep it a secret from their subjects to keep them calm. Because when they say negative things that can cause concern or fear, that's a big mess.
As much as possible, if there is something bad happening that their constituents should not know about, they will immediately find a solution, and when it is resolved,
they might as well tell the real story.
