I mean we still can. I remember some bricks being chewed up like a dog went at it. But, nope, it was just wee little me.

Right?!?

I never got one in a single set as a kid.

Ever since the Yellow Submarine set, we call them the Yoko Ono, because it can break up the Beatles.

Absolutely.

I only knew about them because my parents would pick up their catalogues since we lived in the sticks and while stores had Lego sets, they didn't have a lot and mostly were the cheaper, smaller ones. It was the only way I ever got Technic sets, too; I still never see those in a physical store.

Apparently, they started giving them away sometime in the 2000's. As a kid, 80's-90's, they did not give them away.

Yeah, perhaps in the 2000's but when I was growing up was in the 80's-90's. And the only place I ever saw them was in a magazine for $1.99. But that's just my experience.
