The alternatives aren't really all that better on the topics that he criticized. If you work at big tech, at that scale, it's inevitable there will be parts of the company you disagree with. From my experience there, as long as your criticism is legitimate and constructive, it'll be well received by Googlers/company, heck some of his criticism pales in comparison to the ones done with memes.
You can simply choose to not work at that scale if they're all making the world worse.
Part of an aspect of sticking to your guns ethically and morally is making choices that leave you worse off. If your ethics align with what is best for you, personally, it's not much of an ethical code
I don't have as thick a skin as you, and I get really dispirited when this sort of criticism is adopted as a personality trait / cause internally. It's barely criticism rather than hyperbolic rancor, and while every good community needs people pointing out the bad, as you note, people know they're working at a big company and should value how we avoid things like JEDI, etc. thanks to leadership.
I tend to agree. There are enough problem alerters without solutions in most organizations that it’s not necessary to amplify one’s lack of solutions or influence with comics.
