Well, iReport is an open source project. If you are an "actual developer" and strongly feel everybody should be iReports instead of Studio, you're able to support it and make it available to everybody else. For my part, I prefer Studio over iReport because I'm involved in several other open source projects and all the others are using Eclipse. I have to admit NetBeans has some nice features but I'll rather have common interfaces between projects - makes adding features much more easier.
