Is JetStream VPN, 自由最快最稳妥 safe?

Low risk

JetStream VPN routes browser traffic through vendor proxy servers and sends its proxy login to any site that asks.

The extension sets Chrome's proxy settings to send browsing traffic through servers fetched from the vendor's APIs, which is its stated purpose. Its authentication handler answers every HTTP auth challenge on all sites with the stored VPN proxy username and password, without checking whether the challenge came from a proxy. A website returning a 401 Basic auth challenge therefore receives those credentials.

Shared hosts - 4 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
