Chinese cybercafes forcibly translate to Linux

The network reported that Chinese Internet cafes in order to "combat piracy" forced to install Red Flag Linux (and not for free, on average it costs an institution $ 700). As is known, Red Flag is the largest Chinese distribution kit which development is supported by the state.

According to reports, a new decree on acceptable OS appeared on November 5. It says that in each such institution must be installed or a licensed copy of Windows, or Red Flag. However, Radio Free Asia transmits that they force Linux to be installed even if Internet cafes already have licensed Windows.

It immediately comes to mind that in this way the government wants to unify and facilitate the methods of spying on users, but this is Open Source, and Red Flag uses the standard package manager RPM. A rootkit can be easily calculated by comparing binary distributions of what is installed in an Internet cafe with the standard Red Flag - so the government is not interested in implementing a rootkit, if it is so easy to detect. Anyway, under Windows, putting a backdoor is much easier.

So the story looks weird. There are, of course, no official comments from the Chinese government.
