That's the problem with Pierre's approach to business. He mixes personnal relationships and customer-ship. You can't forbid the access to a new set of cans to a customer because he shared a view on your work (the way you handle your shop) online.
That'd be like Ferrari telling a client "no way you'll drive the f12, you've criticized the way our cars' build quality...". That'd be scandalous, wouldn't it?
