The US doesn't have a great firewall they force all data to go through which they utilize to weaponize javascript served from their own companies to international citizens. China does this. They used their great firewall to modify Baidu javascript to serve malware to international users to turn web browsers into a DDoS against github. All because github hosted projects that allowed Chinese citizens to read the uncensored web.

So, no, you can't trust anything hosted in mainland China. And, no, it's not the same as the US.
