They are wrong. This is a contested grammar rule that was based on one persons opinion in the late 1800s.
There are plently of examples where less and fewer are used interchangable.
Personally I disagree. “Fewer” is more verbose than “less,” so it just looks cumbersome to me.
It also irks me a bit, because I know of some of the instances I see are likley based on the above misunderstanding and not taste.
