That is slightly bizarre restriction, but can be worked around by naming the app "AppName Pro by Developer".
Another work around is to create a pro app and offer in-app purchasing to upgrade to a pro version, at least your profiting from your existing user-base and they know they are not paying for this ripped off version without realising.
AppName Super-Pro?
Or AppName Hyper-Pro? That way it'll be ahead of the rip-off version alphabetically.
