Agreed, but in the American context, "fighting" union creation usually means a little more than just sharing informative messages.

"I heard Donny got both kneecaps busted after he passed out a union flyer last year" said the manager conveniently holding a baseball bat from the "baseball club" he just so happened to be involved in.

I think this is legally the case in most places, but IMO it is extremely unfair to give ownership acting through the corporate entity the same rights as employees, which are actual people.

Sure. the complaint here is not that Amazon shared anti-union messages. (and gets murky when it tries to force employees to consume said messages)
