even with ads blocked "for malware protection", malware could end up being promoted within content, or just encountered somewhere, and there's more actual malware protection (some is built in to OS). so...it's not about "blocking malware" with blocking ads altogether, is it. especially when a bunch of ads are non-interactive and not even about software but stuff like food and other things. it's more about not seeing ads at all.

and sometimes, ad blocking just isn't an "anti-malware" solution in itself. like, if you wouldn't be able to navigate app catalogues and kinda sus out what could be malware or just steer away from untrustworthy apps altogether, ad block isn't gonna help you much there. "native" ads (promotional content) throw an even bigger wrench into that.
