This must be some confusion. I didn't fork anything. Besides, it's not 
useful to fall into the pattern of finger pointing.

That would be a tenuous point to make in more than one way. Druntime was 
a major effort to foster runtime standardization made by its author 
himself and with intentions that I consider most transparent. I'd find 
it very difficult to concoct a hypothesis in which Sean comes across as 
not acting in the best interest of the D community.

That very concern - the best interest of the D community - has 
unequivocally been the reason for which Sean and other chose to leave 
petty fights to others and join Phobos, which has no political agenda. 
That's supposed to tell someone something. You are gladly invited to 
attempt to convince me otherwise, but the sheer facts at hand would make 
it difficult for you to build a case. I mean it's possible - for any 
number of good reasons - to ignore mounting evidence for some time, but 
at some point the waking up and smelling of the coffee is inevitable.

There's no reason to get up in arms. I didn't blame anything on anyone, 
just stated my view of the state of affairs. I'm hardly vested 
emotionally in the matter so I'm not interested in dramatic posturing, 
assigning blame, or drawing sweeping conclusions. One thing I would be 
interested in is improving things going forward. I think that will be 
possible once we all let bygones be bygones and see what we can do to 
push D forward.
