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.
Bit of a sidenote, but Vivaldi is just another Chromium browser. If I had to use Chromium, I’d rather use the Ungoogled fork, even if it’s not perfect at removing everything Google because they’ve made themselves so damn pervasive in the codebase.
