Tennis fans generally do call it "Marseille" or the "Marseille Open" (if you read any British media, the "Marseilles Open"), because it's the more permanent name. Most tournaments have a sponsored name too, which is liable to change frequently and confuse us, and that's the name that's naturally used on the marketing and website.
I don't see any problem in it being called "Open 13". There are worse examples, such as the Stockholm tournament, which has been called "IF" (name of an insurance company) for the last few years.
