No, this is the result of studies on users. People shown their News Feed with relevant ads regularly mention that this was interesting content and do not point it out as ads. This is not an exception, but common for brands with certain characteristics. One example of that is music of film trailers. They however regularly describe as Ads and resent the presence of content that was not sponsored (at least not to Facebook). MLMs and “influencer”-type of content is a caricature; other objections are more idiosyncratic. There are some ads that are seen as such, but those are generally from brands who don’t use Facebook self-optimisation tools or insist on a reach that doesn’t make sense (typically, solution vendors). Overall, sponsoring isn’t correlated with interest.
