Well.

Lest you forget that modern computing exists because ATT built unix and then threw it out to the public, at speed, as they drove away from it as fast as possible. (Something about being an actual monopoly...).

There is at least one thing, on that list that I can almost assure you will be coming back (in concept and spirt) in the next 5 years. Likely open source, because google tossed it...

Meanwhile it has other very public and open winners: Golang, Kubernetes being two stellar examples of them not dropping something like a hot potato.
