Earlier quoted context omitted.
You are free to do whatever you like. And others are free to do what they like. Which for most people includes making judgements about who you are based on the clothes you wear, the car you drive, the style of haircut etc. And buying a Cybertruck does imply that you either (a) agree with or (b) are ambivalent about Musk's behaviour.

People express their opinions all the time in what they purchase or how the express themselves. Should we be blind to it?
