An Open Question to All Autodesk Bashers

In the continuing debate over proprietary file formats one question as been asked over and over again. So far I have not come across any satisfactory response. I came across the following comment when researching content for an earlier post wherein I claimed that there were people who considered the ODA as a “hacker’s group”.

“A ‘non-profit group’? Rather a group of hackers paid by Autodesk competitors. Why have these companies refused to open their proprietary formats when they demand Autodesk to do it? It is just about competition and profit, not user rights.”

Take a look at the ODA members. From the list of founding members, apart from Bentley and Robert McNeel and Associates, I do not know any other company which has opened their formats.

I ask all you Autodesk bashers: Why have these companies refused to open their proprietary formats when they demand Autodesk to do it?
