I've seen plenty of "documentaries" which were really just pushing an agenda. You can distinguish advocacy from accuracy usually within the first few sentences.
Documentaries are usually painfully open about their agendas, like changing policies in Madagascar to save the lemurs, save the smokers, save the obese, etc. But no documentary until "The Billion Dollar Code" ever made me feel genuinely lied to and outright manipulated, and there's no way I would have known if I hadn't read the primary materials. When I discovered the deception, I edited the Terravision Wikipedia page to mention SRI, so there's clues for the next person who enjoys the series, but someone would have to write truthful secondary sources in order for the article to be improved further. Who can say who benefits from poking Google Maps in the eye. Netflix must have been tripping when they approved that one.
Which is also said about anything that tends to go against the views of the other side. It's a bit of entertainment "based" on true events. Nobody claims it is the gospel according to.... They even qualify this in the interview I linked.
The majority of people have no idea on how/when/where the products they use on a daily basis originated. By the time a FAANG type of company releases something, you can pretty much be assured there are casualties along the way.
