It can be pretty frustrating when people debate in this fashion about work-related matters. E.g., nowadays I find it particularly tiresome when people frame technical discussions (such as one database platform or front-end technology versus another) in moral terms. It's incredibly unhelpful.
It has the potential to be even more disruptive for non-work matters (though the original "Best names ever" discussion was very much work-related).
Still, whilst I'm not especially critical of the position DHH and JF have taken - though initially I found myself back and forth on it - I do of course wonder if a more nuanced resolution that alienated fewer people (I don't mean on twitter and other social media, which is mostly just noise: I mean at Basecamp) could have been found than something that feels like blanket ban, even though it's not really.
Perhaps they tried - I don't know.
