Companies are huge and they can hurt many people at scale. Individuals are small, relatively powerless and easy to manipulate. Especially if they don't organise themselves. Spreading information is the first step of getting organised.
I would not encourage people early-to-mid-career, to do this.
I've had recruiters claim that if I use the offer they got me to negotiate a raise from my current employer, they'll make sure I never work in this town again - and yet recruiters keep calling.
Maybe it's less prevalent than it has been in the past, but managers hate "troublemakers," even if the "troublemakers" are 100% correct.

I have known many people that have picked up and moved across the country for "the dream job," only to return, a couple of months later, tail between their legs, because the job turned out to be unsuitable in any of a dozen different ways (usually, it was because the duties did not match what they were told, but I know of at least one case, where the pay was drastically reduced, or they were hired as a contractor, even though they were told it was a salaried employee of the corporation).
