It seems to me like the disagreement isn't as big as you make it out to be. This is an instance where the maintainer of a business has strong views that they consider well-informed on the social impact of an issue, and there is no pragmatic barrier to taking action according to their values, so they are doing this. Inaction in this case might be reprimandable, but I am not saying that I reprimand them or you for neglecting other social issues or anything like that. I am sympathetic with the idea that we cannot all have well-informed views on everything, and that we might not want to act based on half-baked views. I think there is a subtle and interesting discussion to be had there.

Thank you for your work on accessibility! :)

adding to that it is difficult to engage in political activism without getting into partisan politics which is undesirable to some.

To clarify, I would narrow my statement, perhaps, to something like this: "inaction [regarding a subject with which you are familiar and are in a position to act on] is a political position".
