What's really interesting to me about these comments is that OP asked how to take Spotify off of their screen for an unspecified reason. Others chimed in saying similar things for the reasons that were important to them. This appears to have offended the sensibilities of some members, who chimed in sarcastically or seriously as to why they disagreed. They were perfectly happy with their Spotify subscriptions but because they disagreed with the other person's perfectly personal reasons to cancel, they were compelled to say something. They have no need to take action on their cars, no desire to change anything, but because someone else did, it bothered them to the point of needing to post.
Calling this "cancel culture" is incorrect in my view. Cancel culture is when a platform or society at large doesn't allow someone to redeem themselves. Canceling a service because it doesn't meet your needs or doesn't align with your values is the free market. To suggest that people who are canceling Spotify are part of "cancel culture" is just wrong. They're part of the free market, which has always allowed people to make individual decisions based on their value set or group decisions to "boycott" a market. In fact, the United States itself has strong foundations in the boycott.
So when someone comes into a thread that really has no dog in the game and tells participants why they're wrong about their personal decisions, I would argue they are just as guilty of "not allowing opposing viewpoints" as anyone.
