I'm talking anecdotally and from my experience here, not as an absolute.

I will upfront admit i am somewhat biased against authority in general, especially what i perceived to be unearned authority (if you wish to be a respected authority, earn it and continue to do so) In this case however I'm talking about "authority" in a professional sense somewhat measured against the success or failure of particular projects or initiatives.

For the most part i agree with you but it seems like you are using the term "anti-authoritarian" as an absolute, as in being against authority is bad in all cases.

At a lot of companies "Critical thinking and standing up for your ideas" is considered anti-authoritarian because the company culture doesn't allow for that kind of autonomy of thought (by design or long term evolution usually).

Your example works in the context of a company that works in a manner that promotes/encourage that kind of person, not all of them do. My personal experience and that of my circle of colleagues and acquaintances, I'd guess that percentage is around 30/70 with the 70% being companies that either actively or passively punish/discourage both of those types of employees.

Which i'd imagine is what @bouh meant when they said "But good employees will hate your company, because you consider them like bad ones"

Anti-authoritarianism is a bad trait. when the authority in question is doing the correct things (for whatever definition of correct you wish to use). "Anti-authoritarianism" and "Critical thinking and standing up for your ideas" are not mutually exclusive.

As with most things it's contextual.
