I can see why he did it. These aren't beginners. They're experienced developers and managers. If you work at one of the top 5 tech companies in the world on a product most of the computing world uses then maybe this shouldn't be acceptable.
Why is it that this is acceptable for Microsoft to publish? It's not and what makes it worse is that it often gets abandoned. If they had a history going back and finishing this or making it better I'd give them a pass, but I doubt without something bordering vitriolic appearing on HN/Medium no one will care.
I think that's the real complaint. Doesn't anyone care about the experience anymore? I feel like it's only Apple who both cares and has executed a strong long term plan for this. I opened my iPhone X and that thing worked. I actually love all the little things they added. It is hard to do that, but it's these little things which make the product special or down-right frustrating when they don't.
