Right. The old adage - if you smell shit all day, check your shoe - seems to apply. If you think virtually every organization is toxic, then the problem probably lies with you.
Ask your boss to take a week long course that will make you significantly more productive, paid for by the company. What is their answer? 9/10 employers (maybe even 99/100) would say no.
I mean, one of the top posts right this moment on HN is about how employers are recording every single keystroke of their WFH employees.

Sorry, my shoes are clean.
"The future is here, it's just unevenly distributed." In a trade where fixing things is a job skill, knowing how to fix things that nobody wants to fix (yet) can be demotivating, even aggravating. Does that make one toxic, or can there be pervasive problems that takes your industry 20 years (epochs in software) to adopt?
"This is crap" is, for a lot of people, a way to say that this is utterly mediocre (aka. not good, and not satisfying).
The OP was questioning the assumption that the vast majority of workplaces are the kinds of toxic workplaces described by the article and some commenters. Not mere mediocrity.
The account in the article and in some of the more negative commenters didn't fit the experience of the person you replied to, and it doesn't fit mine either. From my (limited anecdotal and not universal) experience and the experiences of devs I know working in various fields, I've seen some toxic workplaces, but they weren't very common and stood out.
I recall talking to (generally younger more emotionally immature) folks who worked at places I've worked. We had good pay, really good benefits, we were on a friendly team with management keeping a light touch. I was happy. They focused on flaws, complained about things like ending free donuts on Fri as though they were living under tyranny, saw things as generally hellish, and were miserable. I've personally seen just what the OP was describing in others. It's worth recognizing that you do get out of things what you bring to them, since not recognizing it is a recipe for misery. If you think everything is toxic, chances are you're bringing something to the story that's causing that.
