Using a non-free (beer) language on a cops-and-robbers challenge

For a discussion on what counts as "free", see this post.

Cops-and-robbers challenges have two components: a cop posts a program optimized to be as good as possible in some property and a robber tries to invalidate the program. An important part of cops-and-robbers is that the robbers can test code in the same language to see if it works to invalidate a cop program.

Although non-free languages would do very well in a cops-and-robbers challenge, they are not within the spirit and introduce an arbitrary barrier to entry. This means that languages which cannot be used freely (as in beer) are banned from competing.

Languages with a free trial that eventually expires are also banned, even if unofficial methods can circumvent the free trial (we don't want companies looking at us and closing the circumventions...).

It should be noted that Mathematica is technically free (as in beer) through Wolfram Notebooks. This doesn't fall under the "no unofficial circumvention" rule as Notebooks is provided officially by Wolfram.
