Imagine that you're a mechanic working on a motor that uses the ProprietaryNew fastener (hex heads? so 20th century!). Unfortunately, the only ProprietaryNew wrenches are made out of cheap metal, and the sockets strip with regularity. You can't imagine saying a few nasty words about the parentage of everyone in ProprietaryNewCo?
From a comment on Twitter yesterday in response to someone, it doesn't seem that Gruber is particularly interested in engaging with this (though I may be wrong). If that is the case I suspect we'll see a forking of the project and we'll get to see whether a committee will do better.
It may well do - Jeff has a good track record at getting things done and is well respected and well liked - but personally I wouldn't put my mortgage on it because as well intentioned as these things are we all know how design by committee usually turns out.
You're right: he just does not give a shit. I can see why. What possible upside could there be to engaging with someone who handles themselves like you are here?
