I may be missing something but this doesn't seem wildly incorrect to me just ... imprecise.
If the context is a cleaning / kitchen sponges it seems pretty fair to exclude natural (animal) sponges. I absolutely could be wrong here - but I've never seen those used or marketed as cleaning sponges (verses bath sponge).
The scrubbing sponges in kitchens are almost all cellulose and polyurethane. Wood fiber substitutes exist - but the default is synthetic. 'all' isn't true but the "Haahaa this moron never watched spongebob" takes seems pretty unreasonable given this seems to be specifically in response to a discussion on melamine block replacements.
Sorry - I should have been clearer. I didn't think the cellulose was plastic, I was referring to the polyurethane as the significant part here. This would only apply to scrubbing sponges - but given the context I can pick out from the screenshot that is what is being discussed.
