We can't have writing that effects clear communication, because nearly everyone is too busy, or too important, or has decided that pretending to be too busy is a way of increasing one's perceived importance, or all of the aforementioned. So they dash off sentence fragments, peppered with inflated vocabulary and buzzwords, and punctuated with ellipses, comma faults, and worse. When the above isn't the case, then you have the people who are too lazy: they cannot be bothered to simply read over to themselves what they've written even one time. And when they aren't merely lazy, then they're simply too dull-witted to understand the need for this. Lastly, you have the people -- perhaps overrepresented in tech -- who suffer from something like an underdeveloped theory of mind. On some fundamental level, they don't understand that what is in their mind is not necessarily in the mind of the reader; and so they lack Clue Number One as to how to establish context. Writing isn't difficult. People are difficult.
