The article linked does not simply "state facts" but rather seeks to what I'm going to call (and for reference I am not trying to positively or negatively spin with these terms and will happily substitute if someone can think of neutral terminology) "soften and justify" why they put things the way they do.
Presidents are human, too, a blend of varying degrees of idealism, generosity, empathy, ambition, ego, vanity, jealousy and anger, but they generally hide their unvarnished traits behind an official veneer. Call it decorum, call it presidential. Mr. Trump essentially calls it fake, making no effort to pretend to be above it all, except to boast that he is stronger, richer, smarter and more successful than anyone else. To him, the presidency is about winning, not governing.
This is basically both "softening/justifying him" (first line, emphasizing that he, as president, is human too and therefore must be having or exhibiting empathy/generosity/etc - it is safe to assume that other words could have been chosen if those traits were not desired to be pushed, even generically positive ones) and emphasizing what he ran on and what he has ruled on in a generic way - perhaps conservatives would say it is too "harsh" and liberals too "kind" as to how he rules, but it fails to take any real stance outside of its existence. It lists multiple controversies and issues that Trump has been involved in during his time but then provides a list of people commenting about it either being good (his supporters, vast and unspecified) or norm-breaking (experts not really followed up with on impacts), all through that section. It's just "this all happened, supporters think it's good, experts think it's new".
There's one direct attack on how he's performed in the third section (Axelrod) - again, couched by other people trying to more emphasize the norm-breaking over anything else. Basically, it all just returns to this cycle of "a Twitter thing happened from Trump, here's how people reacted". There's nothing actually taking him to task, nor any explication as to what damage has been done or will be done by these tweets - just handwringing over whether or not it will do anything.
I'll be honest - it mainly reads to me just like an article that wanted to engage in omphaloskepsis over how "it's changed the American institution of the presidency" without significant factual discussion outside the generic twitterstorm and lashback, or discussion of some of the more extensive damage he's wanted to/trying to do to governmental institutions. I don't think puff piece is unfair because it fails to really do anything outside of "It's a thing, look at it", more or less; "Trump did a thing with social media, people said yay, people said boo, this may change things." I'd expect better writing except I know not to bother from most institutions nowadays. Given both that his twitter dogshit is the least offensive thing he's really doing (which is incredible) and that even if you wanted to focus on media and communication there's infinitely better examples (trying to control how many departments communicate to disturbing degrees, perchance?)... It's trying to write, I think, about the long term effects of the presidency, but fails to really do even that. If you're writing on such a topic, one may want a thesis beyond "things change and he's doing things that will change things" - but that's all the piece comes down to.
