I reject the supremacy of code and standards over social norms
Maybe you meant this abstractly, but this quote seems to imply that you think social norms hold weight in arguments about features on the fediverse. Specifically, that the idea of “requiring consent” to federate posts means bridges must be opt-in rather than opt-out.
What I’m trying to express is that there is no social norm that can apply to the fediverse because it is not a single group. Therefore, any argument that uses social norms to dictate features on the fediverse, as a whole, are wrong. I am extremely in favor of ppl having the tools to control their own data and even build social groups where norms can be used to enforce things, but I don’t think that applies in this instance.
