"Psiphon is a robust and popular circumvention tool that provides users with open access to the internet, bypassing censorship and restrictions imposed by governments, organizations, or internet service providers.
With a focus on privacy and freedom of information, Psiphon enables users to securely navigate the web and access blocked or censored content. Its best feature is its robust network infrastructure, which comprises a network of servers strategically located around the world. These servers act as access points for users, allowing them to connect to the internet through various entry points, further enhancing privacy and anonymity. Psiphon offers a user-friendly interface that makes it easy for users to connect to the Psiphon network and browse the web securely. Users simply need to install the software on their device and with a single click, they can establish a connection and begin accessing restricted content."

FAQ

A lot of long-winded gobblety gook to obfuscate they're running open
proxies. How many proxies they have depends on the number of volunteers
willing to run the software (and hopefully don't run afoul of the TOS
with their ISP regarding running of public servers). How well dispersed
are the proxies all depends on the number and location of volunteers.
VPNs have had their exit nodes mapped. So have the Tor exit nodes. Any
site can block a visitor using a VPN or Tor exit node. There are lists
of the exit nodes usable as block lists. Doubt it would difficult to
map out these open proxies, too. Even if you are trying to circumvent
their geofencing, any site can block connects from mapped nodes. DNS
servers can block you from getting to the proxy unless they only use IP
addresses (so a DNS server is not involved). Perimeter servers can
block you (e.g. Great Firewall of China).
Also remember that when using anyone's entry and exit nodes (might be
the same node, like for open proxies) that the operator of that node
sees your network traffic. You have to trust someone you'll never be
able to identify.
In addition, when using VPN, Tor, or public proxies, you're adding more
nodes in your route to the destination, and the slower is the
connection.

Is this not a free service to users? What is PSIcash used for? When I
visit the buy.psi.cash they show in their FAQ, I get to a site that
blocks my access, and says I need to use the app for access. Shortening
the URL to https://[www.]psi.cash gets "not found" by the DNS server. I
can get to https://my.psi.cash/login (found with an online search on
"psicash"), but I don't have an account to get further, and I'm not
creating one. I was trying to determine just how PSIcash is purchased.
From what I found, you can get some PSIcash by visiting select store
sites. Geez, wasn't there a browser toolbar that tried to do the same:
gave you online searches, but also advertized?

So, is Psiphon operating open proxies, or managing a VPN network? Looks
like this is another bait service: free is low bandwidth, and you pay
for higher bandwidth tiers. I've seen this with some other similar
service: free with low bandwidth, pay for higher bandwidth, and the
freeloaders were, in fact, getting used with parallel connects by the
paid tier users (i.e., the freeloaders were providing the mess network
for the paid users to get higher bandwidth). Who was that?
Not only do you slow your network speed by adding more nodes in the
route between you and the destination, but you get low bandwidth unless
you pay for more. Oh, goody, just what I want: free with a carrot on a
stick as bait to move faster.
I'll pass on this claimed free VPN network.
