Too many tech people have that "I want to slowly lead you to the point like Sherlock Holmes mystery" style of writing, and it is such a time-waste. Arthur Conan Doyle was paid by the word, you aren't. Please, everyone, back to middle school: State a Thesis in your first sentence and THEN expand on it, don't force me to spend pages trying to figure it out.
The "abstract" of a journal article is supposed to contain all the key points of a science experiment including the results, but it's too rare that they do.
I think some folks are just hitting their limits, and needed more time to digest/ review their publication.
Other folks are doing it I obfuscate or pad their work, for whatever reason.
Picking the right level to communicate such that you avoid clickbait journalists spreading a lie of omission/ hysteria is an art. Personally, I think we should be grateful for all the effort put into clearly communicating all the most relevant nuances; we can generalize that any high complexity field is doing its readers a service when it approaches communication this way. I'd rather the "result" be communicated at too high a level than too close to the middle (giving the illusion of understanding the nuance)
