From the article:

• Only 23 E-Mini's have been delivered so far
• All the E-Mini's will be delivered by the end of June
• BMW has the cables but bureaucratic red tape in some cities keeps them from being installed due to disputes about certifications
• BMW plans to have the high voltage cables installed by the end of July
• Customers won't be charged lease payments for their cars until the cables are installed

So basically E-Mini lessees will get a free month of EV ownership. I would say that is a very equable solution put forth by BMW. Lessees could easily rent a car with the $850 savings from not making a lease payment

Send one to me. I'll use it for free for a month.
