AWS literally did that. They paid for full time developers to contribute back to the redis code base, including core redis developers. If you actually look at the redis code base the majority of it was written by people who never worked for redis.

Thats a really big deal, how did they legally managed to do the license change? I was under the impression that only works if the original owner is the doing most work

Permissive licenses don't protect against projects that decide to change the license when releasing a new version.

Copyleft protects against that as a general rule. However some projects that rely on copyleft require contributors to sign license agreements granting the project owners a more permissive license.

Almost all of these license changes just change the terms under which _new_ work is contributed - which is why many of them have forks from the last OSI-licensed commit.

Now that makes sense, so its legal because the contributors can still access their code
