Then you should be denied the opportunity to publish. Corporate obstinacy should not trump good science.

Software is unique in that it can be generally be duplicated and executed trivially.

There's no way to make it trivial to reproduce a test on the strength properties of a new ceramic. There is a way to do this for software, and it's rather silly that it isn't standard scientific practice to do so.

I realise I'm taking a strong line here, but I've never seen a good argument against it.

The unfortunate answer is that instead of harder-to-reproduce science, no science would have been published in all of those cases. Quite often, sharing knowledge is a secondary goal to achieving the set goals of a project. In niche fields, input from any source is welcomed gladly, as long as the papers are sound. Banning corporate players from sharing knowledge in your journal if that's the majority source for input in the field is not really an option.
