I didn't think the BBC did advertising.
The BBC is publicly funded, visitors to BBC news from outside the UK will get served ads.
Maybe I'm confused. Are you talking about the Instant Pot story, or the ads around the story? I'm seeing a Car Fax ad, an ad for a movie, a t-shirt company ad, some other google ads and some ads promoting other BBC properties.
Having worn a foil hat for a while myself, I still find occasion to put it back on every once in a while. Question everything. Never stop asking yourself how you really know what you think you know.
In life, like in software, never trust your inputs.
