The AGPL makes code less usable than MIT, BSD, LGPL and even GPL:

Anything you can do with a piece of AGPL code you can also do with the same piece of MIT code. The opposite is not true.

The reason GPL works so well on Linux is because it doesn't affect licensing of the software that runs on top of Linux or connnects to it. AGPL works around.

The whole point of the AGPL is to ensure that derivative works give users the exact same rights that they were intended to have. It doesn't make the code less usable unless you'd like to make a proprietary derived work.

I know that. What I say is that it seems to me AGPL stifles code reuse more than it powers it.

The alternative to AGPL software isn't necessarily no software or only non-free software but often code with much simpler licenses.
