In the last years, I have seen plenty of users telling or promoting certain ultra-permissive rules as part of Open Source but which are not even in the definition like the use of read-only licenses, being a good example the MEGA software.
However, I didn’t find exact source of these ideas and only believed in the misinformation of certain videos in *tube or similar.
Today, I was looking for a FLOSS VPN client to use at home as I use MATE DE and found Printunl Client promoted as Open Source. Or that was everything until I read the license.
I have never heard of Riseup VPN, but I will take a closer look in the future. Looks definitely interesting though I am somewhat concerned about the lack of information about Riseup VPN on the Internet so far. Seems to be recommended enough, but it will take me some time to be persuaded probably.
