And my point is, if you take from a public repository yours is public too.

If you take, you give.

You're arguing for increasing developer freedom by removing their ability to issue the license of their choice?

There are licenses that provide no restrictions and licenses like GPL that do. Developers should be free to offer whatever licenses they want on their code.

Just because you like a particular kind of license, doesn't mean you should be able to make everyone who publishes a public repository use that license.

Have you seen the Ms-PL? It appears to be deliberately GPL incompatible while also having a similar list of conditions as the MIT license. I think it should be the default license for public repositories.
