Betrayed
Think about people with Apple products. They have the Macbook, the iPhone, the iPad, the Apple Watch, and own several different models of iPods back when they were relevant. When people fall in love with a brand, they tend to stay loyal to it. This man constantly got mad at companies that he felt betrayed by.
He expected everyone in the family to follow his hatred. Therefore, his son always had to learn how to master a new product instead of sticking with brands that he was familiar with. He realized when he was older than some things, like laptops, don’t have the longest lifespan and it’s normal for them to crash eventually.
