If people would ignore fake news, we wouldn't have so much misinformation issues, people biting the onion and flat earthers.
Focusing on net income was meant to keep inexperienced reporters from being bamboozled by IR/PR departments that sometimes went to crazy lengths to find something positive in the midst of a crummy report. (One tech company with dwindling sales, profit and market share liked to talk about its strong cash position.)
Of course, that was in the days before up-to-the-second updates on after-hours trading. So now reporters know the market's verdict within a few minutes of the earnings release. That leads to financial-results stories that hunt for something (earnings? revenue? next quarter outlook?) that explains the stock movement. In this environment, different metrics get different levels of prominence all the time.
I wouldn't burn up a lot of energy coming up with conspiratorial reasons why reporters pick different numbers. Inexperience and confusion usually are the simple reasons for 90% of strange decisions. This is probably true in a lot of areas.
