Wait wait wait. I think there may be some misunderstanding of what free SW promises.
Free SW is a software that grants
freedom, not
security. This freedom includes the freedom to escape malware. It is therefore a
prerequisite for security. A basic idea to build upon.
Security is an extra step. You can start something that builds a repository of secured software on top of free SW. It would probably be something like a package manager, with only signed packages. It would be based on free SW, not competing with it.
Any software marked as Open Source is malware by default unless proven otherwise.
I agree that what's marketed as open-source usually has catches (openwashing, non-free platform requirements etc.) and has to be double and triple checked. Just as RMS says, they stripped the idea of the ethics and freedom part. From my experience, SW marketed as free (as opposed to open) SW is basically 100% okay.
It’s time to start a war on Open Source.
If you ask for my personal opinion, wars are never good. Passive resistance is what I choose. Stick to ethics, stress it as your priority, educate it, deny anything unethical.
