count on no fingers

[Noriko Tan]

Hi
I just wanted to know the meaning of this sentence:
"Unstructured communication always falls back to email or chat. You can count on no fingers the amount of products who have changed this over the years"

I know "count on fingers" means "rare", but here the author used "count on no fingers", does it carry contrary meaning? like "there are a lot of products which have changed this..." ?

It means that there are absolutely no products which have "changed this over the years". If you tried to count the number of products which have "changed this over the years", you would need no fingers at all to count on.

It is not contrary at all.

Where did you find the original text? It should have used "which", not "who".

Me too was confused about the subject he's talking about because he used "who" instead of "which".
the original article here (under the subtitle "where should we start?").
