Speaking as a non-merchant and non-professional 3D Artist, I guessed there was more to it than "Personality".

A few days ago, when I saw the-now-irrelevant-to-AM licence which was on the now-obsolete CP webpage for AM, it read that the content fell under the Poser EULA. 

When I read further down that text, it said that the company does not enforce the rights of the third-party content providers.  Also, that copyright remains with the third-parties.  The text makes a distinction between what content is developed by the software owners, and those of third-party providers.  I am guessing third-party refers to the bundled content (such as the runtimeDNA stuff, the Blue Moon Studios stuff, some Zygote stuff, etc etc).

Which, in my mind at that time, meant that those creators would have to bear the brunt of any litigation / protection of their IP rights.  Add that to other commercial issues such as what Anton has posted on his own website.  A formula for discontent.  Well, I guess it went over the edge for Anton and so, AM moves once again.

I hope eveyrthing works out for everyone this time round.  It will be good to move on.

I don't have any idea how CP run their business with their content-providers, and I don't want to talk about that.  I don't bear any ill-feelings towards CP;  I'm just another little customer of theirs, who likes some of the things they sell.  Just sharing my view on the case.
