Most everyone knows the rules in VietNam
After twenty-one years here in VN, and with heavy involvement with the InterNet, web products and admin/modding 40+ chatrooms (for money) I have never had a visit from the Ministries of Culture, Information or Internal Security.
First of all, FB is - supposedly - a blocked site in VietNam due to the type of content. ISPs here do block it, although VNPT Mobile users can access it. Any youth over 10 knows how to set-up/use VPNs. The UK and France both block more web sites than VN.
DINH Nhat Uy is a fool. He didn't get locked up for using FB, he was locked up for criticising the government in the way he did. NEVER criticise government personalities, ministries are OK.
The courts here are similar to the ones in Britain - opinionated. They are sensitive to the social scene, again as in Britain. I have used the courts several times and found the judgements equitable. Penal code section 258 is used by prosecutors not, as Muncaster said, by the courts.
We have two types of charges, as do most countries: Summary/Misdemeanour and Felony. The Cong An (Peoples Police) handle Administrative charges - drunk driving, fighting, minor theft, etc. Sound familiar? The 'records' of such charges are destroyed after one year. In the USA, UK and Canada, etc. such records are retained often for life. Which would YOU prefer?
Felonies are handled by the courts and the records remain for life.
Police don't feature in peoples lives here, we don't hear "Hey you" followed for a demand for ID. Neither do we have the cops pulling people over as happens in Canada, UK or USA. I frequently travel 350 kilometres overnight, at speed. but I never get checked. And the cops hang out at every toll gate.
Decree 73 isn't onerous, it requires .VN domains be hosted on a VN domiciled server. It will require Yahoo and Google to set up token servers here. The English translation of 73 aren't the greatest, Vietnamese loses a lot in translation.
Western 'social' sites have experienced difficulty with personal data being abused and misused. VN has strict controls on the use/copying/retention of personal data. My wife owns two hotels and we require guests to complete their own registration forms; our employees complete their own government forms - which means the data supplier 'volunteered' the information.
Reading 73 without knowledge of VN law distorts opinions.
P.S. Like most people in VN I am apolitical, my wife is apolitical, only the most dedicated people have time for politics. As a Canadian I know Western 'freedom', both the UK and USA have far more onerous police states than either Canada or VietNam.
Why are so many Foreigners living here if they don't regard VietNam favourably?
