Normally I'd agree with you.
Except you are literally coming in here with a thiny-veiled 'but my moral high ground!' stanning for a guy who used a free trip to a fan event to...
1) Not do any research beforehand (if he was actually being honest about not knowing anything, which is still pretty damn bad considering what his job is)
2) Wasted everyone's time by asking the highest level SE staff involved with the game a public question that could have only resulted in two kinds of answers, one very clickbaity and one generic non-answer for very obvious reasons
3) Is on record to have harassed multiple attendees at the event and disparage the efforts they put into their creative cosplays
4) Wrote an asshole article about the fanbase after the fact, and little to nothing about anything that was announced pertaining to the actual game
I mean, nothing about this is even for legitimate journalistic works like criticizing how the company handles its finances or time management, or DLC practices, or anything. The guy made a conscious decision to screw with a fan gathering involving high level SE staff in full view of many other journalists in attendance as well (who probably had actual questions to ask and had to listen to this douchebag trying to bait the staff into saying something clickbaity). You literally have to go out of your way to screw this up.
Maybe if the asshole isn't interested in the actual game itself, maybe it stands to reason that he and the rest of the site should be completely blacklisted from anything SE-related. I mean, they probably wouldn't miss not being able to cover any future SE products or being able to review something like KH3 in a normally starved month like February at the same pace as actual legitimate websites, if multiple people in the staff decided they can afford to be this disrespectful towards a fan gathering of all things. (Again, consider that someone made the decision to send this ONE person, and someone else must have read over their colleague's article and decided this was a perfectly okay thing to publish instead of telling off this colleague for being a dumbass.)
SE doesn't have to suffer fools, and neither do we.
