I know that (at least: I know it is so in the Netherlands. Getting to grips with international IP laws is teeth-gnashingly frustrating

), but considering I have been using the artwork they commissioned, that I was originally planning on sharing my cards and the fact I was posting them on a public forum, I feel they are justified in requesting me to stop sharing them.
And since they cannot control whether or not I would share them in secret after all... Let's just say that there are companies in this industry who would put the hammer down with a lot more force than the friendly message I received. Official cease and desist letters, threats, fines etc.

So, considering the above; no matter if they are legally entitled to demand my stopping completely or not, morally they would have a point (at least I think so). But instead, they acknowledged the work I have already put into my designs, and they have no issue with me proceeding, even though they have no control over what I eventually do with them.
Oh; and just to be clear to everyone; I will not be breaching that trust by making any exceptions...
