The comment you're replying to is, I think, sarcastic. The point being that the Amazon employees aren't that stupid and can think for themselves. Maybe they're just not interested in joining a union that Amazon could easily allow to walk out and hire a different set of unskilled workers.

Your sibling comment is the patronizing one.

Thanks, yes. I was being exceedingly sarcastic.

I do very much believe that by-and-large Amazon employees adults in their warehouses who can think for themselves.

(The weasel phrase 'by-and-large' is in there, because in any big enough group of people you'll always have a few fools, and their existence shouldn't detract from my argument.

And also perhaps Amazon also managed to hire some people with real medical / clinically diagnosed cognitive impairments and give them productive jobs. The latter would be great news for diversity and inclusion, and just general humanity.)
