> Is this the cancel culture apocalypse the right is talking about?
Asking people to not separate the product from the person, and think that the guy does not deserve any praise for his work because of some association with people that disagree with you? Yes, that's cancel culture that (not just) the right is talking about.
Trying to label everyone that holds an opposing view as "hateful" without absolutely no room for dialog? Yes, that's cancel culture that (not just) the right is talking about.
> it's not ethics anymore?
Does Soapbox come with some kind of clause that says you need to share their views to use their code? Is the product itself exclusionary in any way? Then no, ethics have nothing to do with it.
