I think those are all fair points but people do things for other reasons than to be negative. For example, I don’t think Dan Dillon made his comment because he’s resoundingly negative on D&D. But he is pointing out that the company fired experienced designers less than a year ago and are now rehiring. They didn’t see a need for designers less than year ago? Companies are not perfect creatures making automatically logical choices - decision makers make boneheaded decisions, and people have a right to point that out when they feel it happened.
It just so happens that the company is releasing a new edition of the game which is always a hot topic for fans that brings plenty of positivity and negativity as the changes come out - that’s expected, really. And on top of that, they seem to be pivoting to a digital medium in a time where tech companies are being increasingly criticized. So yeah, they’re gonna be a lightning rod for criticism too.
And while you may be blasé about corporations, and expect the worst so why bother talking about it, surely you cannot expect others to take things as resignedly as you. People gripe on imperfect information all the time, and sometimes it’s overblown - and sometimes it isn’t overblown. Sometimes the defenders of the company’s decisions are underplaying the downsides of whatever topic is at hand.
I see your overarching point. Both sides of an issue should be carefully examined before 'picking a side'. But even then... the concept of picking a side... yikes. No one is right or wrong 100% of the time. Rail against the wrong, but at least acknowledge when right is done. This is how everyone wants to be treated... because everyone makes mistakes.
So that Dan Dillon thing... maybe it was a numbers problem (as in the corporate decision, for reasons beyond an individual's performance, but yet important to the health of Hasbro or WotC as an organisation, cut staff as part of an overall cost-cutting measure... which is how these things happen btw... costs are cut across multiple aspects of a company... it might be staff, it might be letting go of a lease on an office lightly used, etc. Usually it's a combination of these.)
Maybe he was a poor performer, or was otherwise a problem to work with, and this was an excuse to let him go. These things happen all the time. Not at all saying this is the case, but I am acknowledging the possibility.
In other words, it's not about
@Oofta seeing things resignedly. He does get a bit Eeyore-ish and curmudgeonly sometimes

He's talking about certain realities of having a job though.
Some of those 'realities' are unfair though, which is I think the point you are making. Those should be called out and discussed. Bearing in mind though, that sometimes people complain about things because they get personally stung without looking at the bigger picture. The world is grey... you make it better and advance causes by understanding all sides of an issue, not by digging in your heels before you know what's actually going on.
