> WINRAR License is least concern for me, because when WinRAR was created, there were different times, when there was an idea, that auhor(and maintainer) should have all the legal rights to his work(and that also includes compensation) - not some company, that is employing talents.

The rights to WinRAR are held by a company, not an individual.

> Also, closed propiertary sources were historically better for security.

This is not true and was never true.

> Also, 7z even nowadays havce some limitations, which requires workarounds, which is time consuming in archive creation.

Like what?
