I'm not entirely certain what you mean by this but I wanted to point
out a part from the Free Software Definition [0]:

"'Free software' does not mean 'noncommercial'. A free program must be
available for commercial use, commercial development, and commercial
distribution. Commercial development of free software is no longer
unusual; such free commercial software is very important. You may have
paid money to get copies of free software, or you may have obtained
copies at no charge. But regardless of how you got your copies, you
always have the freedom to copy and change the software, even to sell
copies."

I recommend reading the entire Free Software Definition along with
Selling Free Software [1].

Depending on what exactly you mean by the programing being "secured"
from commercial use, it may mean that it doesn't qualify as free
software to begin with.

On the other hand, if you mean 'commercial' as a synonym for
'non-free' or 'proprietary' then I'd like to point you to [2].

Yes, the FSF has it in its list of GPL-Incompatible Free Software
Licenses [3]. Plus, there's also [4].

There was a discussion on a new version of the EPL [5] but it seems to
have stalled. Regardless it would be good to help raise GPL
compatibility as something to be addressed in the next version of the EPL.

Until/less that happens perhaps some sort of exception is appropriate?
It may be best to contact licensing@fsf.org for help with such a thing
because it can be hard to get them "just right."
