The fine is actually 200 yuan, but the salary, over 1 million yuan, which he received while working remotely has been deemed as "illegal income" and subject to confiscation.
And then a third party, the government, who had no part in this, took money from him. No matter how it was assessed, was a fine.
I do wonder where the employer is in this picture. Who are they? Do they not protect their employee? It's well known that VPN and GitHub is banned in China, did they make this netizen use the VPN and the illegal service knowingly? Did the netizen use these knowing it's illegal, or were they misled to believe they have legal access? Was the employee a remote contractor of sorts?
