legalize over legalize

You think this conflicts with Stallman's ideals? Did you look at Stallmans comments regarding Russian maintainers[1]?

For those too lazy to click, the relevant bits of his statement are:

"... The precise requirement is that users be free to make and distribute copies of their modified versions as free software. Those Russian have a moral right to distribute copies of their modified versions of Linux. But they have no moral right to demand that the Linux developers use those changes. Whether you use someone else's changes should be up to you."

There is nothing about Stallman's "Four Freedoms" which require that kernel developers lend technical assistance to sanctioned entities. Which is what the sanctions (which are being promulgated not just by the US, but also by the European Union, Switzerland, Japan, and other countries) are all about.
