Compare this behavior with Jeff Bezos. For all his faults, he did something infinitely classier. He actually bankrolled a news organization that has a global presence and practices journalistic excellence - and did not try to meddle in its editorial policy beyond that (or if he did, it was so subtle as to be unnoticeable).
The goal of journalism is to "afflict the comfortable and comfort the afflicted", so why should publishers not take a critical stance toward some of the most comfortable people in the history of humankind?
If there's something happening in tech that worthy of criticism, criticize it. If there's something worthy of praise, praise it. And for the rest: report it. Only presenting negative things is about as useful as only presenting positive things. But it feels more journalistic, "speaking truth to power" and all that. It's not, negativity just sells better.
But no, of course, it was because they had "questions" and everything in tech is Adam Neumann and Theranos.
