The KI Media site is outside Cambodia, I think they might be in the US. Government critical, Vietnamphobic. Same goes for Khmerization. If the sites are obviously directed against the government and Vietnam they might well be affiliated with the Sam Rainsy Party.
Sam Rainsy used to be finance minister in the CPP and got kicked out because of his anti- Vietnam rants. He got replaced by Keat Chhon who was SR's enemy in the CPP. And who's reputed to have been a death camp commander (similar to Duch, there were 4 or 5 of them in the country but only Tuol Sleng, S- 21 is well- known).
I don't read it much.
Have a look at the comments and you'll see what kind of people it appeals to
Re the other website, I don't know it. It looks ok but with journalists in Cambodia, it's like with everybody else.
They're poor, they need to make money. So they can be bought and they themselves can extort and blackmail.
Check Reporters without Borders, they have a list of press freedom, one every year.
Cambodia ain't doing too bad if you compare it with similar countries or even with its much more developed neighbours.
I agree that I would have never believed that I could have made several trips to Cambodia so quickly after the end of all of the Democratic Kampuchea business. While the infrastructure was not top notch (roads, electricity...), it was incredible that people who had suffered so much could smilingly be ready to welcome visitors to their country when their own lives were still miserable.
Of course, if the Khmer Rouge had destroyed the sites of interest to tourists, I believe that development would have been much slower.
