You are free to bash Tesla over the head as much as you want and tell as many people as you want that Tesla is horrible and to not buy their cars even though you love the car itself. If you are successful enough, Tesla sales will falter, the company will go under and then you'll really have problems getting warranty work done. I would think there are more constructive ways to get the management's attention but if you feel sabotaging sales works for you, go ahead. I'm apparently a mindless cheerleader so you understand things on a much higher level. If I was getting ulcers over my anger at Charter cable for example eventually I would just switch to something else. Tesla doesn't make the only car in the world so if they anger you that much, if management sucks and is not trustworthy and the service is terrible most people would walk away at some point. Some people enjoy being in that place though so have at it.
