EULA aside, what a shame it would be if Jan B decides there's no € in it and stops maintaining Refox any further.

Apart from tweaks for more recent Windows versions and digital signing, my own experience is that when some of us confirmed the hook technique to crack most forms of protection for VFP apps, Jan B was *very* quick to respond with a competent anti-hack in Refox. Had he not done so, all those people Refoxing their apps believing they are preventing easy decompilation, would be wide open. So Jan has to know (and we want him to know) that he will be rewarded for this sort of improvement.

My personal test for unethical/improper behavior, is "what would happen if everybody did it." In this case, we too might save a few $ if just a few licensees paid Jan and then onsold use of Refox for a small fee, but there wouldn't even be a Refox if we all did that. Therefore it seems to me that onselling use/avoiding license fees only is possible as long as everybody else behaves properly (pays for a license) which means it fails the propriety test IMHO.
