That's not the kind of spatula they're talking about, I've rarely seen that kind be black. I'm pretty sure they mean the flat offset kind you'd use to flip eggs or pancakes.
OXO makes a flat silicone spatula too (I think they call it a turner or something), I've got one and it's been a great upgrade from the black plastic kind.
Plus it won't scratch anything enameled or nonstick etc.
in english in america, can't speak for other lanuguage/locales and too lazy to look, the word spatula is used for two different tools:
one tool is for scraping food (generally solid) inside a hot frying pan
the other tool is for scraping foods (generally liquidy generally cold) from the sides of a bowl or other container.
in the first case you want to flip your pancake and it's sticking to the pan
in the second case you want to get all of the pancake batter to pour into the frying pan.
The picture is the article is of a hot frying pan black plastic scraper.
GP's picture is a silicone cold bowl scraper.
is the disconnect
it is potentially true that you should eliminate all such spatulas made of "plastic" hot or cold, and it is potentially true that in all cases substitutions with silicone is the right move, but I'm not sure if that's what is being suggested
We have the same word for both in France, like you.
However we have an extra word for the silcon one to get all the pancake batter: marise. It is not used very much, though, outside of some cooking books or shows.
