Notice it says "our current jars". The current jars don't take canning
lids.

I have gotten rid of all my old mayonnaise and Miracle Whip jars (at
least I don't *think* I have any left.) I will keep using my Atlas jars
until they break or I lose them; they look and feel to me every bit as
thick as Ball and Kerr jars. You'll have to decide for yourself.
