On the 30th anniversary of the announcement of Linux by Linus Torvalds, Red Hat has said that it all worked out because of the way the OS was licensed.

In a post today celebrating the anniversary, Red Hat said: “The reason that Linux has been arguably the most successful operating system of all time is due to the fact that its license allowed copying, improvement, distribution and required sharing of changes. (Note that the license does not require collaboration, but the reciprocal nature of Linux strongly encourages it.)”

Now Google reckons security isn’t good enough, and Android is proprietary
