1. It's just my opinion, by I find things like this always reflect incredibly poorly on the author, especially since the author appears somewhat clueless as to why someone would think it would show them in a bad light. It would be one thing if there were some egregiously bad behavior (e.g. stories of Adam Neumann come to mind, as do the recent articles about Ozy Media leadership). But this basically just comes off as a bitch session: the CEO is rich, he did a bad job announcing the layoffs, we got no severance, etc. etc. When that happens, you say "fuck that guy" and move on. Nobody really cares about your laundry list of slights.
2. Now, all that said, I normally only see missives like this where leadership tries to build a false emotional bond with employees: "We're a mission-driven company, we're changing the world, we treat each other like family, yada yada." So some (usually less experienced, less jaded employees) take this message to heart and truly do form an emotional bond with the company, so when business conditions change and there are layoffs, they take it incredibly personally. Thus, my point is really that leadership only has themselves to blame when they cultivate a "we're a big family" vibe and then are surprised when people are extra pissed that their "family members" are kicking them to the curb.
Just a bit of advice: treat your employment like business, because that's what it is. You can work hard and take pride in your work, but also understand that you might get cut if the business need arises. Getting laid off always sucks, but I think it's easier to do if you have a healthy detachment from work.
