I can agree with him on things like lack of a fancy wysiwyg, but workflows? Multi side admin? Pay someone to implement that for you if you don't want to do it yourself.
A simpler more effective plugin system (current one is an unmitigated mess).
Others cool stuff have been added lately such as drag and drop uploads.
This guy is expecting to have someone coding a custom software for him just because it's available with GPL license. Non-sense.
