Here’s the problem with your car analogy, it talks about a car that is broken or has been advertised as something it’s not. D2 is neither broken nor falsely advertised. You simply are unsatisfied by your purchase. It’s like eating at your favorite restaurant and finding out the recipes have changed and you no longer like the food (I’m looking at you Olive Garden). You certainly have the right to tell the manager that you are dissatisfied and why but you don’t have the right to make a scene in their place of business much less to come back daily and attack their employees or their customers who do enjoy the food. That, in the real world, gets you immature ass arrested and put under a restraining order.
