EntoCon 2013 International Conference on Entomology 2013 OMICS Entomology Symposium 2013 etc. At any rate I think you're interpreting the accusation quite narrowly; the assertion is that OMICS has repeatedly done this and/or performed other actions that wilfully intend to confuse and deceive (e.g. associating authors with their conference without permission). The battle isn't being fought over a hyphen in isolation.
