It's unethical. Content incompatibility between Studio and Poser is unavoidable. Eventually, yes, you are correct, they eventually must go in different directions. In the meantime, we as their customers (meaning CL and DAZ customers) need to see support for what is already out there on both sides until we decide which of the two programs best meets our needs. As for whether or not it is a rip-off, I'm not sure. Cross-compatiblity is common in software programs. For example, Corel Painter opens native Photoshop files (it has since the beginning). It does a lot of the same things as Photoshop, but it also does its own things as well. Same with Word and WordPerfect (each can open the other's file format). We will probably see Poser format support in DAZ Studio until it has enough of its own community support to rest on its own laurels - mainly because of the investment DAZ already has in Poser-compatible content.
